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.
Also cellular respiration is an aerobic reaction meaning it require oxygen to take place and releases a CO2 by product. In the experiment aged water was used as the control. The CO2 and O2 levels were tested and used as the base level coming in at 7.6ppm for O2 in Table 1 and 12.3 ppm for CO2 in Table 2. Three variables were set up with controls.
+ ATP Although plants and animals have different methods of obtaining glucose, the cell respiration process occurs in both types of organisms. Many external factors in the environment may affect the organism's’ rate of respiration such as the temperature of the surrounding,
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.
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.
Glucose provides energy for the cell. This occurs in the cytoplasm, produces two ATP, and does not require oxygen. Following glycosis next is the citric acid cycle. This stage occurs in the mitochondria, and produces two ATP and carbon dioxide. This step does not require oxygen.
What is cellular respiration? Cellular respiration, distinguished by two different types-aerobic (with oxygen) and anaerobic respiration (without oxygen), is a four-step procedure that describes the metabolic processes that occur in our body to break down, or catabolize, organic molecules, such as glucose, to assist in the production of ATP, or Adenosine Triphosphate. ATP, or Adenosine Triphosphate, as the name states, is a compound, or nucleoside, found in DNA and RNA, made up of one purine called adenine, a pentose sugar, and in this case, three phosphate groups. What is the purpose of ATP? The purpose of this compound is to release free energy, derived from the catabolism of glucose and oxygen, during the hydrolysis (the water is part of
The Krebs cycle and electron transport are two processes that are essential for a cell to function and to create ATP. The Krebs or citric acid cycle is a process that occurs in the matrix of the mitochondria after pyruvate is completely oxidized. It completes the breakdown of pyruvate into CO2. The cycle is the central metabolic pathway in all aerobic organisms, yet it does not use oxygen in order to produced ATP. The electron transport chain is also located in the mitochondria, but takes place in the inner mitochondrial membrane or the cristae.
In Cellular Respiration, cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration. In fact, most of the energy used by the cells in your body is provided by cellular respiration. The process begins when glucose in the cytoplasm is broken down into smaller molecules. This releases a small amount of energy.
Four organelles that should be present in the eukaryotic organism are the nucleus, mitochondria, chloroplasts, and ribosomes. The nucleus stores genetic information/DNA. The mitochondria acts like a digestive system and it’s where cellular respiration occurs. The chloroplast converts light energy into sugars, which is used by cells, this is the process of photosynthesis. The ribosome is the site of protein synthesis.
An integral part of the study of biology is the study of cellular respiration and photosynthesis, which are both essential processes in living things. Without these pathways, living things would not survive as the intricate methods of converting energy into fuel are conceived in these two processes. The main purpose of both of these concepts are to form adenosine triphosphate (ATP), a molecule that contains the energy to fuel organisms. Though similar in goals, photosynthesis and cellular respiration have a lot of differences as well. The main difference between the two is that photosynthesis occurs solely in plants but cellular respiration occurs both in plants and other living organisms.
Cellular respiration happens in both eukaryotic and prokaryotic cells. The three main stages of cellular respiration: 1.Glycolysis - this is the splitting of sugars. It has glucose, a 6 carbon sugar is separated into 2 molecules of a three carbon sugar. This happens in the cytoplasm of the cell. During the process, two molecules of ATP, and of pyruvic acid and 2 electron carrying molecules of NADH are created.
