The Krebs Cycle and ETC enable the cell to produce 34 more ATP molecules per glucose. The 62 percent of the total energy of glucose that is not used to make ATP molecules is released as heat.

Why is more ATP generated from glucose in the presence of oxygen?
when oxygen is not available, the Krebs cycle and electron transport cannot produced, and glycolysis produces just 2 ATP molecules per glucose molecule, under acerbic conditions, the Krebs cycle and electron transport enable the cell to produce 34 more ATP molecules per glucose molecule
Differences between anaerobic respiration and aerobic respiration?
Aerobic Respiration is a respiration of a bacteria with oxygen. Glucose + Oxygen --> Energy + Water + Carbon Dioxide Anaerobic Respiration is a respiration of a bacteria without the presence of oxygen. Glucose -- > Energy + Carbon Dioxide -----by vigneshsherlekar Aerobic Respiration is a respiration of a bacteria with oxygen.

What is the process of breaking down sugars in the presence of oxygen?
aerobic respiration basically its first step is called glycolysis and is further divded in two forms either aerobic which occur in presence of o2 and anaerobic in absences of oxygen Exactly so to answer the question the process the REQUIRES O2 is aerobic respiration like i said.
Cellular respiration releases energy by breaking down glucose in the presence of what?
Oxygen!
Cells produce ATP most efficiently in the presence of what molecule?
Oxygen. Cells can produce much more ATP from glucose in the presence of Oxygen (aerobic respiration) than without oxygen (anaerobic respiration) in a process called oxidative phosphorylation that occurs in the mitochondria of cells. In the presence of oxygen one glucose can be broken down to produce 36 ATP Without oxygen, only 4 ATP can be made
Where does most of the heat generated by the body come from?
The heat that is generated by the body comes from the food you eat. The oxidation of pyruvic acid (from glucose) into CO2, water and energy is called Krebs cycle. This cycle occurs only in the presence of oxygen. Hence it is an aerobic process. It takes place in the mitochondria.
The complete breakdown of glucose in the presence of oxygen yields how many molecules of ATP?
36 molecules by oxydative phosphorylation.
Can cellular respiration and fermentation be used to release energy?
No. Either cellular repsiration or fermentation can be used to release energy depending on the presence or absense of oxygen. When oxygen is present, it acts as the terminal electron acceptor in cellular repritation, followed by the release of energy When there is no oxygen present, other organic molecules (like lactic acid) accept the terninal electron and energy is generated
Can a cell undergo respiration when glucose is not available?
Yes, it can in a process called anaerobic respiration.
What substances need to be available for mitochondria to function?
Mainly there are two requirements.They are glucose and Oxygen.
What organelles convert glucose into energy with the presence of oxygen?
mitocondria the powerhouse of the cell. the process is called aerobic respiration
What are 2 reactants of cellular respiration?
Oxygen and Glucose =P
