Introduction: Absorption can be defined as a process of uptake of nutrients into the circulatory system of the body. The process of absorption occurs after the digestion of food.
Answer to Problem 1TY
Correct answer: An animal absorb nutrients from recently ingested meal during the absorptive state. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
The absorptive stage includes the ingestion of various nutrients into the blood from the alimentary canal. During this state, ingested minerals and nutrients play an important role in the supply of energy to the body.
Option c. is given as “absorbing nutrients from a recently ingested meal”.
Recently ingested meal supplies energy during the absorbing state of an animal. Hence, the correct answer is option c.
Reasons for incorrect answer:
Option a. is given as, “fasting”.
Fasting can be defined as a state of abstaining from having food items. During this state, nutrient is not absorbed at all. Hence, option a. is incorrect.
Option b. is given as, “relying entirely on stored molecules for energy”.
Animals rely on stored molecules for energy in fasting state instead of the absorptive state. Hence, option b. is incorrect.
Option d. is given as, “
The process of metabolizing stored lipids in adipose tissues for supplying ATP occurs during fasting state and not during the absorptive state. Hence, option d. is incorrect.
Option e. is given as, “doing both a and b”.
During absorptive state, an animal obtained energy from the ingested meal and not during fasting state. The process of metabolizing stored lipids in adipose tissues for supplying ATP occurs during fasting state. Hence, option e. is incorrect.
Hence, the options a., b., d., and e. are incorrect.
With the absorption nutrients from the recently ingested food during the absorptive state, an organism is able to meet the energy requirements.
