Question

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
A) ATP is used for long term storage,while fat is immediate energy.
B) ATP used for short term energy and builds molecules of starch & fat.
C) fat & starch is unstable and can be stored short term, while ATP is long term.
D) Fat and starch are stable if used as energy immediately , while ATP is long term storage

Answer 1

Answer:

because it is hard to breakdown fat in a very short time while

The ATP can be broken down fat in a very short time. ATP is mainly usedwhile doing short bursts of exercises.

so I think the answer is B

Answer 2

B) ATP used for short term energy and builds molecules of starch & fat.

Explanation:

• The ATP or adenosine triphosphate is an instant form of stored energy obtain from glucose. This is available for obtaining energy for immediate actions.
• The ATP readily dissociate into ADP and Pi this process releases energy. This is due to the simple structure of ATP.
• But starch and fat are the complex molecules which require more amount of energy to break these bonds. Thus these molecules remain available as a stored form of energy and requires time for energy production.
• Thus this can be said that ATP is a short term energy source whereas the fat and starch is the long term energy sources.
