What is the yield from complete oxidation of glucose?

What is the yield from complete oxidation of glucose?

8.7: Energy yield by complete oxidation of glucose

Reaction Comments Yield of ATP (moles)
glucose → glucose 6-phosphate consumes 1 mol ATP −1
fructose 6-phosphate → fructose 1,6-bisphosphate consumes 1 mol ATP −1
glyceraldehyde 3-phosphate → BPG produces 2 mol of cytoplasmic NADH
BPG → 3-phosphoglycerate produces 2 mol ATP +2

How many ATP are produced from 1 glucose in aerobic respiration?

38 ATP

What is the net ATP gain from one glucose?

Why do plants not use ATP?

Why don’t plants use ATP as their immediate source of energy? Short answer: Because they cannot — ATP must be manufactured before it can be used as “cell fuel” (energy).

Why do plants make glucose instead of ATP?

Following are the reasons why production of an energy molecule such as glucose is essential: Not all parts of the plant are photosynthetic. These non-photosynthetic pzrts need an alternate source of energy. Since ATP is unstable, it cannot be transported to different parts of the plant without degradation.

Do plants still use oxygen in order to produce ATP?

This last step requires oxygen, and therefore is called aerobic respiration. Thus, the final result of cellular respiration is that the plant consumes glucose and oxygen and produces carbon dioxide, water, and ATP energy molecules. The plant needs energy all of the time.

Why is ATP a better immediate energy source than glucose?

It is much more energy efficient to add and remove those phosphate groups than to add and subtract elements from a glucose molecule, as there is no way to effectively break it down without significantly changing its structure, which makes it harder to build back up.

Why is ATP the best energy source for human beings?

Finally, ATP can be deemed a good energy source as it has the ability to transfer a phosphate group, and therefore energy, to other molecules.

Is glucose an immediate source of energy?

The immediate source of energy for most cells is glucose. But glucose is not the only fuel on which cells depend. Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.

Does glucose have more energy than ATP?

Explanation: Given that the oxidation of, for example, glucose ( C6H12O6 ) by cellular respiration can produce 38 ATP, it would follow that there is more energy in a molecule of sugar than a molecule of ATP.
