when rate of transport is at full capacity, carrier proteins are said to be

○ hypersonic.
○ crenated.
○ inactive.
○ hypertonic.
○ saturated.

Explanation:

To solve this, we analyze each option:

• Hypersonic relates to speed of sound, not transport proteins.
• Crenated refers to cell shrinkage, irrelevant here.
• Inactive means not working, but full capacity implies active use.
• Hypertonic refers to solution concentration, not protein state.
• Saturated in transport context means carrier proteins are fully occupied (all binding sites used), so transport is at full capacity.

Answer:

E. saturated.
