Which two of the four macromolecules, do you believe to be the most important for life? Give evidence to support your suggestion (include a full description of the macromolecules) Describe both in terms in structure and function.
From my study of macromolecules I decided to choose proteins and carbohydrates as my main two macromolecules. To me they are the most important two. Carbohydrates are important because they are a source of immediate energy and controls structure of cells such as cell wall etc. Without this source of energy the animal body could not carry out the functions properly so this is why carbohydrates are so important. Now proteins have many uses for example enzymes and transport proteins. Proteins provide support for example keratin which gives structure to hair and nails. From the information I have gathered it will show you my point of view and my reason why I believe these are the two most important

Glucose (C6H12O6) which is the most common monosaccharide. The molecule has a carbonyl group and multiple hydroxyl group. Depending on the location of the carbonyl group, a sugar is either an aldose or a ketone. Glucose is an aldose fructose is a structural isomer of glucose is a ketone monosaccharides, particularly glucose are major nutrients for cells. The process of cellular respiration, cells extract the energy stored in the glucose molecule (Campbell & Reece, 2005). The molecule is a sugar that provides major fuel for cellular to work. But the carbon skeleton works on the row material for synthesis of all different verities of small organic molecules. For example amino acids and fatty acids. Such sugar molecules that are not immediately used are incorporated into disaccharides and polysaccharides. Glucose which is a monosaccharide has a structure of rings. To form a glucose ring, carbon 1 bonds to the oxygen which is attached to carbon
Dionna Johnson~ Chapter 2 Paper Monosaccharides are the simplest form of carbohydrates, and they're the simplest form of sugar also. Monosaccharides are the main block of complex carbohydrates, such as disaccharides and polysaccharides. They appear in a crystal-like substance, and can dissolve in water. Molasses has a high content of the monosaccharides. Yogurt contains monosaccharide galactose, cherries contain monosaccharide fructose.
Energy is also needed to circulate blood, breath, take in oxygen, make new cells, grow, repair, and to transmit nerve impulses to react to changes in the environment. For example, moving quickly to get out of danger or recognising the best course of action to take in an emergency situation. Energy is also needed to build complex molecules such as enzymes and hormones from the simple molecules produced after we digest food and drink. A constant supply of energy is needed by the body and cells to enable all of these activities, and without this energy we would be unable to function as living beings.
The glucose in your blood comes from carbohydrates in your food. Carbohydrates include sugar and starchy foods like: bread, pasta and rice. Keywords: Carbon dioxide, Glucose, Water, Oxygen and energy.
Carbohydrates are important as they are an energy source. Carbohydrates are all about energy and are found in foods like fruits, vegetables, breads, pasta, and dairy products. The energy source in these products come from the body turning them into glucose. Proteins are needed in the diet because they are needed for growth and repair and you need it to make enzymes,
Carbs and fats are needed in the diet for energy but proteins are not intended to be used as energy. What do they do for the body instead? List a few of the functions of proteins. Type your response here: Proteins do so much for the body. They help with your hair and nails.
The body uses glucose for energy. Glucose metabolism requires insulin a hormone produced by the pancreas. When we eat, our food is broken down by our digestive track into nutrient molecules. Foods containing carbohydrates, protein and varies sugars are then broken down into glucose. Glucose is used for many different organs in our body as fuel.
Alzheimer’s disease, the most common type of dementia, results in damage to the brain. Alzheimer’s disease affects over five million people and is the sixth leading cause of death in the United States. A brain of a person with Alzheimer’s disease will have fewer neural cells and connections between those cells than a person without Alzheimer’s will, resulting in decreased memory and a decline in cognitive abilities. This type of damage can be better understood and possibly prevented through the implementation of the appropriate drugs by examining the roles of differing types of chemical bonds in Alzheimer’s disease. Proteins, which are the building blocks of all organisms and are responsible for multiple cellular functions, can only accomplish
Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.
DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
Introduction: The purpose of each experiment is to test which macromolecules are present in each of the different pieces of food, with the foods being apple, potato and hot dog. These experiments, in total, will test for the presence of three of the major four macromolecules, carbohydrates, lipids and proteins. The following are my hypotheses concerning each of the experiments: Carbohydrates - The apple will react, the hot dog will not react, the potato will not react. Starch - The apple will react, the hot dog will not react, the potato will react.
Sugar/ glucose is an important carbohydrate that can be made during photosynthesis from water and carbon dioxide, using energy from sunlight. Carbon dioxide is given off as a waste product when energy is released by the breaking down of glucose. This can be used by plant cells in the process of photosynthesis to form new carbohydrates. Yeast is a single-celled fungus that can break down sugars (glucose) to help produce carbon dioxide. Research Question
In uncommon occurrences, disulfide bonds between cysteine deposits in various polypeptide chains are included in balancing out quaternary structure. Proteins are connected with numerous capacities all together for a cell to support its life. The accompanying is a rundown of capacities that are done by proteins: * Proteins are essential auxiliary segments in cells: actin, myosin and tubulin are proteins found in the cytoskeleton. *
The Universe is an ever-expanding void of space littered with particulates essential to understanding life, as we know it, and as we discover it. Astrobiology is concerned with the study of life on Earth and in space, how life came to be and its evolution, and whether it can be sustained on other cosmic objects. The only way we can determine if life can be sustained on other planets is by looking at the our own: identifying sources of organic compounds, of which are vital to the evolution of life, studying the macromolecules in the origin of life, mapping the habitability of our planet it its early years, examining the evolution of life as we know it, and its corresponding environments during different stages of life, and then constructing
