Final answer:
True, glucose enters cells through facilitated diffusion, a process that utilizes carrier protein channels within the cell membrane.
Step-by-step explanation:
True, glucose entry into the cell is by facilitated diffusion. This process involves the movement of glucose down its concentration gradient through carrier protein channels in the cell membrane. Unlike simple diffusion, facilitated diffusion requires these specific protein channels to allow substances to enter or leave the cell. There are various transport proteins like GLUTs that are responsible for the facilitated diffusion of glucose. Once inside the cell, glucose participates in metabolic processes such as glycolysis, which prevents it from flooding back out of the cell.
