In the absorptive state, cells use ______­___ to produce ATP?Question 31Select one:a.fatty acidsb.glucosec.glycogend.cellulosee.amino acids

To answer the question, let's break down the options and understand the context of the absorptive state:

1. Absorptive State: This is the period during and shortly after eating when nutrients from food are being absorbed into the bloodstream. During this time, the body prefers to use the readily available nutrients for energy.

2. Options Analysis:

   • a. fatty acids: While fatty acids can be used for ATP production, they are more commonly utilized during the post-absorptive state when glucose levels are lower.
   • b. glucose: Glucose is the primary source of energy during the absorptive state because it is readily available from the digestion of carbohydrates.
   • c. glycogen: Glycogen is a stored form of glucose in the liver and muscles, used primarily during fasting or between meals.
   • d. cellulose: Cellulose is a type of fiber that humans cannot digest and thus cannot be used for ATP production.
   • e. amino acids: Amino acids can be used for energy, but they are primarily used for protein synthesis and other functions during the absorptive state.

3. Conclusion: Given that glucose is the primary and preferred source of energy during the absorptive state, the correct answer is:

b. glucose
