Why are skeletal muscle cells able to take up glucose without insulin during exercise?
A)Muscle contractions can activate movement of glucose transporters from the cytoplasm to the cell membrane.
B)The cell membranes of muscle cells contain glucose receptors.
C)Muscle cells can take up glucose without insulin.
D)Muscle cells do not depend on glucose transporters for uptake of glucose.

During exercise, muscle contractions stimulate the movement of glucose transporters from the cytoplasm to the cell membrane, allowing for the uptake of glucose without the need for insulin. This is an important mechanism for providing energy to the muscles during physical activity.
