Glucose is an important biomolecule. which of these statements is true regarding the movement of glucose into and out of cells? a) glucose, a small molecule, can diffuse between the phospholipids. b) glucose requires both a membrane protein and atp energy in order to enter or exit a cell. c) glucose, a nonpolar molecule, can pass freely across the phospholipid bilayer from high to low concentration. d) glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.

D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.

Explanation:

Glucose is a polar, large, and hydrophilic molecule that cannot easily diffuse the cell membrane. It moves across the membrane through a mechanism known as facilitated diffusion. In this process, a carrier protein attaches itself to glucose molecule and transport it without any use of ATP. Instead, the movement is driven by concentration gradient. An example is the diffusion of glucose in red blood cells.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
