Question

the diagram shows four types of transport. which process requires energy and is necessary for maintaining homeostasis? o l o m o j o k

Explanation:

1. Analyze each process:

• Process J: Molecule moves through the lipid bilayer from high to low concentration (simple diffusion), no energy needed.
• Process K: Molecule moves through a channel protein from high to low concentration (facilitated diffusion), no energy needed.
• Process L: Molecule moves through a carrier protein from high to low concentration (facilitated diffusion), no energy needed.
• Process M: Molecule moves from low to high concentration (against the concentration gradient) with a carrier protein, which is active transport. Active transport requires energy (ATP) and is essential for maintaining homeostasis (e.g., moving nutrients in or wastes out against gradients).

Answer:

M
