Question

Glucose and amino acids move in or out of a cell by _____. passive diffusion facilitated diffusion active transport endocytosis and exocytosis

Answer 1

Glucose and amino acids are polar hydrophilic in nature. Hence, both molecules will be repelled by the hydrophic core of the phospholipid bilayer, made up of non-polar fatty acid tails. For such molecules to pass through the phospholipid bilayer, it requires a carrier transmembrane protein to provide a hydrophilic channel for specific polar molecules to enter.

Endocytosis is uptake of liquid or solid from extracellular matrix (usually large in size or large in volume)

Exocytosis is the release of substances out of cells. (usually hormones/chemicals/proteins)

Hence, ans is faicliated diffusion
