Recommended: Introduction to cellular respiration

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 two reactants in cellular respiration are glucose and oxygen. Cellular respiration has three products as a result of the reactants. They are carbon dioxide, water, and energy in the form of ATP. Cellular respiration takes place when living things convert glucose into cellular energy. The location of cellular respiration is in the cytoplasm and mitochondrion. The significance of cellular respiration and photosynthesis is they both help living things grow, develop, and stay alive. …show more content…

Mitochondria and chloroplast need energy to perform their jobs. Both of them are in plant cells. The reactions take place in these two organelles. The chloroplast has stroma which is a sticky substance where the Calvin cycle happens. Mitochondria is where the Kreb’s cycle takes place. The cytoplasm in the mitochondria is where glycolysis takes places. These organelles are there for one purpose which is to keep us alive. The Calvin Cycle and light dependent reactions perform in different places and have different purposes. Light dependant reactions take place in the grana. The grana is the stack of thylakoid. During this process the grana combines the sunlight’s energy and water in the stroma then it splits water to release oxygen. It makes ATP to power the Calvin Cycle. The Calvin Cycle happens in the stroma. The stroma is the region outside the thylakoid membranes. This process happens when it takes carbon dioxide from the atmosphere and ATP to produce

the nuclear membrane is a double membrane structure that acts as a barrier separating the nucleus and the cytoplasm. 4. Mitochondria- termed as the “powerhouse of the cell,” the mitochondria is responsible for the production of ATP and cellular respiration. Energy is converted in this structure and used for the different activities that take place within the cell. 5.

Transcript of 02.06 Introduction to Photosynthesis Light-Dependent Reaction : The energy releasing, light-dependent reactions of photosynthesis turn light energy into chemical energy. Which transfers this energy to ATP and NADPH, this then happens in the stacks of thylakoids of chloroplasts. ATP and NADPH are needed for the energy that is used in the light-dependent reaction.

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.

The glucose will be used in cellular respiration for energy and some of the oxygen will exit the plant through the stomata to provide the world with air to breath (Simms, 2017). Cellular respiration is the next step which is a light independent reaction which takes the glucose and some oxygen from photosynthesis and produces CO2 and H2O. The balance of

The purpose of this experiment was to see what the effects of light and dark would have on photosynthesis and cellular respiration. With the knowledge gained in class about how both the reactions took place. It was predicted that the absence of light would slow down photosynthesis causing less O2 to be released in the water. It was also predicted that the beaker with the fish in the water would yield a higher concentration of CO2 in the water. These predictions were made based on the fact that plants use the energy from light in photosynthesis to split H2O creating an oxygen by product.

Advanced Biology Photosynthesis Lab Report By Cheryl G11 Introduction & Background Photosynthesis is the process by which light energy is converted to chemical energy. It occurs within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process. Plants use photosynthesis to produce their own food (glucose), some water and the oxygen that we need.

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the granum, in the chloroplast. In the light-independent reactions or Calvin Cycle, the energized electrons from the light-dependent reactions provide energy to assemble carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin Cycle because carbons are constructed into carbohydrate molecules in a cycle of chemical processes. Even though the light-independent reactions do not use light as a reactant, they require the products of the light-dependent reactions to function.

Photosynthesis and Cell Respiration form a complete cycle fairly simplistic. If you look at the equations for each system, you'll see that they oppositely reflect each other. The equation for Photosynthesis is: CO₂ + H₂O ⇾ Sugar + Oxygen. During Photosynthesis energy from the sun is required. Whereas, the equation for Cellular Respiration is: Oxygen + Sugar ⇾ CO₂ + H₂O (Which releases energy from the sugar).

The Chloroplast contains green pigment called chlorophyll which absorbs light energy from the sun. That is where the first stage occurs, which is known as, the light-dependent reaction. This stage takes place in stacked thylakoids, known as the granum. The light-dependent reaction is highly dependent on light energy. The products of this stage are light, water, and carbon dioxide.

The chemical equation of photosynthesis is 6 CO2 and 6 H2O and that makes 6 O2 and C6H12O6 . What is not expressed in the chemical equation is the capture of energy from sunlight which occurs. Photosynthesis uses electrons on the carbon atoms as the repository for that energy. Respiration is the opposite of photosynthesis. It reclaims the energy to power chemical reactions in cells.

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.

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.

Chloroplasts are organelles that carry on photosynthesis; carbon dioxide diffuses into the chloroplasts in the leaves (Mader, S. 2010). Sugar and oxygen are released during the process. In order to photosynthesize, plants depend on light energy from the sun. The rate of photosynthesis will increase or decrease depending on the colour of light being absorbed, blue light results in the most photosynthesis occur and green light results in no photosynthesis occurring.
