Facilitated diffusion is accomplished using transport proteins. Transport proteins are channel or carrier proteins that are attached to the membrane and are specific to different molecules. The diagram shows carrier proteins that bind to the molecules and change their shape in order to move the molecules across the membrane into the cell's interior.
Which of the following best describes facilitated diffusion?

Facilitated diffusion uses passive transport because transport proteins require ATP to move molecules across the cell membrane.

Facilitated diffusion uses active transport because transport proteins require ATP to move molecules across the cell membrane.

Facilitated diffusion uses passive transport because transport proteins do not require ATP to move molecules across the cell membrane.

Facilitated diffusion uses active transport because transport proteins do not require ATP to move molecules across the cell membrane.

The sodium-potassium pump is a carrier protein found in the cell membrane of all animal cells. The diagram shows how the carrier proteins act as the pump that moves potassium ions into the cell and sodium ions out of the cell.
Why is this process considered active transport?

A molecule of ATP activates a molecule of ADP. The ADP transports the ions across the cell membrane.

The carrier protein breaks down ATP and uses the released energy to move the ions across the cell membrane.

The carrier protein uses ATP and uses that energy to move the ions across the cell membrane and against the concentration gradient.

The ATP transports the ions across the cell membrane with the concentration gradient.

A diagram of removing glucose from the blood by a fat cell is shown.
Which statement best describes the role of insulin and glucose-transport proteins in the process?

They keep the plasma membrane flexible when glucose is removed from the blood.

They stimulate a response from white blood cells during glucose entry into the cell.

They utilize the excess energy the cell produces to create more glucose.

They help to maintain stable glucose levels both inside and outside the cell.
