Photosynthesis and cellular respiration2/11/2024 ![]() Enzymes also play a big role here, adding any additional phosphate to ADP then resulting in more ATP molecules. The Krebs cycle takes place in the mitochondria, it takes the two pyruvate molecules that were in the previous cycle to then turn them into two ATP molecules, they do this by oxidizing (or adding oxygen to) the pyruvates which then makes CO2, which is why we breathe out CO2, this all creates a by-product of two more NADH molecules. ![]() Stage two of cellular respiration is the Kreb cycle which does require oxygen making it aerobic. Since glycolysis only needs glucose to work and not glucose and oxygen this makes it an anaerobic process meaning it doesn’t need oxygen, unlike the next 2 stages. Glycolysis is breaking up glucose molecules and turning them into pyruvic acids this process uses two ATP molecules but then produces four more ATP molecules along with two NADH molecules (which helps with making ATP). ![]() In order for cellular respiration to take place two things are needed oxygen and glucose., once you have those two ingredients the first stage glycolysis, takes place. There are three stages of cellular respiration, glycolysis, Krebs cycle, and electron transport chain. Cellular Respiration is when oxygen and glucose are taken in and covered into ATP energy in the Mitochondria, ATP energy fuels the cells and provides energy in the body. Despite this, there are also differences possessed between these 2 processes. These two processes work together hand in hand as a global balance since they are reactants of each other. Cellular respiration is organisms obtaining energy from a conversation that releases energy when oxygen is present. Photosynthesis is known to be performed by plants, as is cellular respiration. The derivative of the word photosynthesis is the process in which energy of sunlight is converted by plants to store chemical energy in carbohydrate bonds. There are two key processes that occur in nature to obtain energy, they are photosynthesis and cellular respiration.
