Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. butchmorris. Save. C6H12O6 + 6O2 6CO2 + 6H2O. Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. Which statement BEST compares aerobic and anaerobic respiration? After glycolysis, the molecule that was glucose enters the acetyl-CoA step of cellular respiration as… a. ATP b. c. Oxygen is required to build the acetyl-CoA molecule. After glycolysis, in aerobic respiration, Krebs cycle occurs in the mitochondrial matrix, followed by oxidation of reduced coenzymes through electron transport chain in the inner mitochondrial membrane.

Respiration is of two types, aerobic respiration, and anaerobic respiration. 11. All tasks and answers are included, can print answers for self assessment. Your answer for this question will be B. Aerobic respiration uses oxygen and makes lots of ATP while anaerobic doesn't use oxygen and releases lactic acid. Aerobic Respiration . This quiz contains questions relating to cellular respiration. You need to be able to compare the processes of aerobic and anaerobic respiration with regard to the need for oxygen, the differing products and the relative amounts of energy transferred: Exam Tip Remember that cellular respiration is not breathing; it is a chemical process of transferring energy from glucose in all living cells. The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Specification Point 2.37 .

Anaerobic respiration does not require oxygen and is defined as the chemical reactions in cells that break down nutrient molecules to release energy without using oxygen; It is the incomplete breakdown of glucose and releases a relatively small amount of energy for use in cell processes; It produces different breakdown products depending on the type of organism it is taking place in I just took the test and got this right so you can trust me. This type of respiration needs oxygen for it to occur so it is called aerobic respiration. Cells respire anaerobically in the body during exercise because not enough oxygen can reach the cells fast enough.
