Question

The process of ________ involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient. the process of ________ involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient. bulk transport facilitated diffusion osmosis active transport simple diffusion

Answer 1

Molecules such as glucose and amino acids can be absorbed from the digestive tract and a renal tubule by the process of facilitated diffusion, which involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient. The process involves a process of spontaneous passive transport of molecules or ions across a biological membrane via specific trans-membrane integral proteins.
