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


Why can 18 times as much ATP be generated from glucose in the presence of oxygen than when oxygen in not available?

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


Why do yeast cells consume glucose much more slowly if oxygen is present than absent?

why do yeast cells consume glucose much more slowly when oxygen is present than when oxygen is absent


what substance do cells need to get energy from food?

When you become more active your cells need more oxygen and glucose, and when your body releases energy, glucose or other organic fuels in the presence of air is called aerobic respiration. aerobic respiration is in the absence of air.


How do you get energy fast?

When you are exercising you use your energy up and that's why you breathe fast but in order to get more energy you need more oxygen and glucose. To get more oxygen you need to breathe faster and to get more glucose you need to eat or drink something containing sugar, because glucose is a sugar.


What is the numberof glucose on the periodic table?

There isn't an atomic mass or number for glucose. Glucose is a compound of 6 Carbon, 12 Hydrogen, and 6 Oxygen atoms. Any more info requires more knowledge in this subject that I don't possess.


Do The products CO2 and H20 contain more energy than does the reactant glucose?

they are they same. the products of photosynthesis are oxygen and glucose and the reactants of cellular respiration are gluose and oxygen.


Does unit of fat take more oxygen to be converted to energy than glucose?

yes


What does cellular respiration occurs in the presence of?

Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.


Why your heart need lots of oxygen and glucose?

It is a large muscle which constantly exercising your entire lifetime. However, the human brain requires even more glucose and oxygen. The brain consumes 20% of the energy available.


How many atoms of hydrogen and oxygen are in glucose?

There are 12 atoms of hydrogen in a particle of glucose
