Question
During the absorptive phase of metabolism:Question 27Select one:a.blood glucose levels are loweredb.it has been some time since the person last ate foodc.the pancreas secretes glucagon rather than insulind.the liver converts glycogen to glucosee.blood glucose levels rise, which triggers the release of insulin by the pancreas
Solution
To answer the question step by step, let's analyze each option in the context of the absorptive phase of metabolism:
-
Option a: blood glucose levels are lowered
- During the absorptive phase, nutrients from a recent meal are being absorbed into the bloodstream. This typically results in an increase in blood glucose levels, not a decrease. Therefore, this option is incorrect.
-
Option b: it has been some time since the person last ate food
- The absorptive phase occurs immediately after eating when the body is digesting and absorbing nutrients. If it has been some time since the person last ate, they would be in the postabsorptive (fasting) phase. Thus, this option is incorrect.
-
Option c: the pancreas secretes glucagon rather than insulin
- Glucagon is secreted by the pancreas during the postabsorptive phase to increase blood glucose levels by promoting glycogen breakdown. During the absorptive phase, insulin is secreted to help cells take up glucose. Therefore, this option is incorrect.
-
Option d: the liver converts glycogen to glucose
- The conversion of glycogen to glucose (glycogenolysis) occurs during the postabsorptive phase to maintain blood glucose levels. During the absorptive phase, the liver is more likely to be storing glucose as glycogen (glycogenesis). Thus, this option is incorrect.
-
Option e: blood glucose levels rise, which triggers the release of insulin by the pancreas
- This is the correct option. During the absorptive phase, the intake of food leads to an increase in blood glucose levels. In response, the pancreas releases insulin to help cells absorb glucose, thereby lowering blood glucose levels.
Therefore, the correct answer is:
e. blood glucose levels rise, which triggers the release of insulin by the pancreas
