Explain how cells obtain energy from cellular respiration?

Answer 1

Cellular respiration is a process that releases chemical energy from sugars and other carbon based molecules to make ATP when oxygen is present. It takes place in the mitochondria. :) -Biology Textbook

Answer 2

Cellular Respiration releases chemical energy from sugars and other carbon based moecules to mae ATP when oxygen is present. It is an aerobic process. As for where the energy comes from, the Krebs cycle jumps in.The Krebs Cycle produces molecules that carry energy to the second part of cellular respiration. Hope this helped! -Biology Textbook

Answer 3

The aerobic respiration is a high energy yielding process. This occurs in all of our cells for energy we will need.

During the process of aerobic respiration as many as 38 molecules of ATP are produced for every molecule of glucose that is utilized.

Thus aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules and uses 2ATP to start the process.

The process of anaerobic respiration is relatively less energy yielding as compared to the aerobic respiration process. During the alcoholic fermentation or the anaerobic respiration (represented in the first equation) two molecules of ATP (energy) are produced. for every molecule of glucose used in the reaction.

Similarly for the lactate fermentation (represented in the second equation) 2 molecules of ATP are produced for every molecule of glucose used. Thus anaerobic respiration breaks down one glucose molecule to obtain two units of the energy storing ATP molecules.

Answer 4

Cells harvest energy from food by cellular respiration. This process is called glycolysis which is when your digestive system breaks food down to release the glucose molecules.
