Foundations of Chemisty in Biology
Prompt Your response
Describe an example of a chemical reaction that occurs in the body. A chemical reaction in the body that occurs is in increased metabolites with just about 10 minutes into exercise. If you consistenly exercise scientists believe there are long-term changes in your metabolism.
Plant Cells
Prompt Your response
Describe the primary structures in plant cells. The primary structures in plant cells are the nucleus, Nuclear Membrane, Cytoplasm, Cell Membrane, Cell Wall, Plastids,

Roles of each consist of the nucleus contain genetic material, which controls the actions of the cell, the cytoplasm is where the most chemical process happens and I controlled by enzymes. The Cell membrane controls the flow to and from the cell, the Mitochondria has the most energy released by respiration. In the Ribosomes protein synthesis occurs, and in the extra parts of the plant structure is functions like the cell wall, which strengthens it. The Chloroplasts contains chlorophyll, it absorbs the light for photosynthesis, and finally the permanent vacuole is filled with cell sap that helps keep the cell …show more content…
The roles are as follows for the bacterial cells, the structure flagella are the swimming movement of the cell, pili stabilizes the cells during DNA transfer, the capsules are used as protection for the cell when a method of killing or digestion is happening. The cell wall confers rigidity and the shape they have, the plasmic membranes are the barriers and the location for the enzyme systems which produces energy. The ribosomes like animal and plant is the factor for protein synthesis. The other functions like the Chromosomes and the plasmid make up the DNA of the cell.
Explain how bacteria cells make energy for cellular processes. Energy between the bacterial cells can be transformed from one another in a development called transduction. The chemical energy stored is called the glucose fuel, it allows the protons to move in and out of the cell. The cell has to waste its own energy and is produce in a similar way that fuel is transferred into a car engine to make it
1. Nucleus- present only in eukaryotic cells, this structure stores most of the genetic information of the cell. The nucleus directs the production of proteins through the synthesis of mRNA. 2.
The cell wall gives the cell structure and so do the beams of the stadium. 3. Mitochondria - The mitochondria in a cell is like the crowd at a baseball game. The mitochondria gives the cell energy just like the crowd does at a baseball game. The crowd gets the players pumped up by cheering and yelling.
The novel The Immortal Life of Henrietta Lacks is based on a poor black woman named Henrietta Lacks who had cervical cancer in 1951. Although such a wide range of cancers all across the United States were present during her time, she, in fact, her cells, were selected and collected without consent or knowledge to develop a so called “immortal cell.” This “immortal cell” has been sold in the billions, in which the Lacks family has received absolutely nothing in return for. They were unknown and unheard of. However, the research and understanding of her cells in order to develop vaccines, immunity, cloning, etc. is the base of some parts of modern biology and medical research today.
Introduction A mutation is a heritable change that is passed from the mother cell to progeny cells. Mutations may lead to good, bad or neutral phenotypic changes in the organism. They may occur spontaneously as in random DNA replicative errors or may be induced by mutagenic chemicals or radiation. Besides mutations, another way that bacteria achieve gene diversity is through the three known mechanisms for intercellular gene transfer.

Slavery is a touch and go topic and everyone has separate opinions on slavery but I don’t think the emergence of the slavery in the English colonies was primarily a response to economics. I feel that it was just pure hate and racism. At this time money wasn’t controlling everything and money wasn’t as important to the world then as it was now. Economics didn’t change once slavery started or ended.
6-5 Short Paper: Classes and Methods Art Penerian IT-145 Application Development Southern New Hampshire University Abstract The purpose of this document is to write a short paper in response to the following prompt:
Cytoplasm is a specially organized solution of salt, nutrients, and complex molecules in water. The composition of cytoplasm may vary among different types of cells, but its purpose is the same – it provides a medium in which complex reactions can occur. For complex reactions to occur, cells need a source of energy.
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.
In cellular respiration, chemical energy that comes from fuel molecules is converted into ADP. ADP join with phosphate, then converts into ATP to form energy currency of cells. Cells release phosphate after consuming the ATP, which join with ADP to renew the cycle. The cycle state is called the glycolysis, electron transport and the acid cycle. They both provide energy that is used by plants, and recycle each other's "waste" for
The cell membrane regulates the deoxyribonucleic acid, enzymes, and it builds a pathways for any reaction such as metabolic. When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport.
The first and most obvious similarity that the two types of cells, plants and animals, share is the nucleus. The nucleus is where the cell’s DNA is stored. This organelle is covered by a second membrane and contains its own nucleoplasm which serves a similar purpose to the cell’s cytoplasm but is inside a nuclear membrane to keep the chromatin from spilling into the cell itself. The nucleus acts as the control center for the cell, maintaining homeostasis, and choosing when to divide. Contained on the DNA is the genetic code for the ribosomes needed for protein synthesis which is crucial to the cell’s life.
Figure 1: Type of cells The fundamental organelles in eukaryotic cell include: mitochondrion that is the powerhouse of metabolism, generating energy by process of respiration in the form of Adenosine Triphosphate (ATP) .It has its own stranded DNA hence able to self-replicate itself and multiply to replace the worn out cells during process of respiration .The mitochondrion is sac-like in its structure. The cell membrane is an organelle with the ability to select permeable substances into the cell hence able to transport desired material into the cell. In prokaryotic cells, the cell membrane is made up of glycolipid and glycoprotein thus providing mechanical resistance to the cell by being the base of attachment for cytoskeleton in some organisms.
Plant and Animal Cells can be similar in a lot of different ways. However Plant and Animal cells can also be different and also be very different in a lot of ways. Some ways that Plant and Animal Cells are alike is because they both have a Nucleus, Nucleur membrane, and a Nucleolus. Likewise they also both have ribosomes, golgi bodies, cytoplasm, mitochondria as known as the powerhouse of the cell, cell membrane, vacuole, and a cromation. In addition they both have a smooth and rough endoplasmic reticulum.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
