The correct answer is a. Facilitated diffusion.

Here's why:

During exercise, like running a marathon, the body needs a quick and efficient way to get glucose (the body's main source of energy) into the muscle cells. This is done through a process called facilitated diffusion.

Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Glucose transporters (specifically, GLUT4 transporters in muscle cells) are the proteins that perform this function.

When the athlete starts running, his muscle cells become more sensitive to insulin, a hormone that signals the GLUT4 transporters to move to the cell surface and start transporting glucose into the cell. This process doesn't require any additional energy because glucose is moving from an area of high concentration (in the blood) to an area of low concentration (in the muscle cell).

So, facilitated diffusion is the mechanism that accounts for the transport of glucose into the muscle during running.
