What happens when mice grown in the absence of microbes are inoculated with healthy cecal material from other mice?
A) Genes associated with glucose uptake, lipid absorption, and lipid transport are activated and the mice gain body fat without increasing energy intake.
B) Genes associated with glucose uptake, lipid absorption, and lipid transport are activated and the mice gain body fat as a result of taking in more food.
C) Genes associated with protein uptake, lipid break down, and lipid transport are activated and the mice lose body fat without changing their food intake.
D) Genes associated with protein uptake, lipid break down, and lipid transport are deactivated and the mice lose body fat as a result of taking in less food.

Question

Quizplus · Accepted Answer

When mice grown in the absence of microbes are inoculated with healthy cecal material from other mice, genes associated with glucose uptake, lipid absorption, and lipid transport are activated, leading to an increase in body fat without an increase in energy intake. This demonstrates the significant role of gut microbiota in regulating metabolism and body composition.
