Photosynthesis and Cellular Respiration are an essential part of human life. These processes are what have kept the Earth a more habitable environment. Without photosynthesis, we would not be able to receive energy. We should be more appreciative of plants, without them we would not survive. This essay will explain the basic components required for photosynthesis, the role of chlorophyll, how energy is transferred, and photosystems I and II and the most precious product results of photosynthesis. Also, there will be some information about cellular respiration. Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. The main components required for photosynthesizing are sunlight, energy, water and mineral from the soil, and carbon dioxide from the air. Once these components are combined they produce two products. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. Not only that it is vital for life, it is also responsible for producing oxygen, which is a large portion of the Earth 's atmosphere. The role of chlorophyll in photosynthesis is vital. Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose. During photosynthesis, chlorophyll captures the sun’s rays and creates carbohydrates
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.
Photosynthesis consists of two stages, the light reactions and the dark reactions. The light reactions convert light into energy (ATP and NADHP) Occurs in thylakoid stacks of grana Sunlight is converted into ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule) Chlorophyll absorbs light energy and starts a chain of
The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).
The leaves then make ATP, which reduces NADP to NADPH, and add CO2 into organic molecules. When the leaves go through the process of a light-dependent reaction by being placed in water, oxygen is created through photosynthesis and is released into the interior of the leaf. This causes the leaf to rise. However, since cellular respiration is happening at the same time, the oxygen is also being used up. This means that the leaves must
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
Alexandra Fowler Due: 10/25/2015 Metabolism Exam Answer the following questions as completely and concisely as possible. Some answers may be a single word, but for more detailed responses, keep you answer to 3 sentences or less. What is the electron donor of an organism growing chemorganotrophically? The electron donor of an organism growing chemorganotrophically is an organic compound such as glucose, acetate, etc.
One of the focuses of this semester was the ability to identify biological processes that require energy and explain why they require energy. In the work I completed I demonstrated being able to accomplish this. This occurred in several different projects, including the cellular respiration lab involving the respiration rate of germinating seeds, the potato core lab and the photosynthesis lab. In these labs, we were able to identify the biological processes that required energy for the different processes to take place to allow germination to occur.
Photosynthesis and Respiration: Cellular respiration and photosynthesis are the two main processes carry out by most living organisms to attain energy. Whereas photosynthesis is performed by most plants that can make their own food, most animals achieve their energy necessities through cellular respiration. Photosynthesis: Light-dependent Reactions and Light-independent Reactions or dark reactions or Calvin Cycle are the stages of chemical reactions during the process of photosynthesis. Light Reactions:
Photosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.
Photoautotrophs are organisms that make their own energy via the sun. These are organisms such as phytoplankton,
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.
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
Photosynthesis and cellular respiration are processes that help human beings live. The reactants in photosynthesis are carbon dioxide, water, and the sunlight’s energy. The products of these reactants are glucose and oxygen. Photosynthesis takes place in the chloroplasts in only plant cells. This is when plants convert carbon dioxide and water into glucose by using the sun’s energy.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
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.
