B)saturation
C)competition

Question

Quizplus · Accepted Answer

Specificity refers to the ability of a carrier to recognize and transport a specific substance or group of structurally similar substances while excluding others.

Answer: B
 Saturation refers to the point at which all available carrier molecules are being utilized and transport rate cannot be increased further, even with an increase in substrate concentration.

Answer: C
 Competition refers to the ability of structurally similar substances to compete for the same carrier and transport mechanism, potentially affecting the uptake or distribution of both substances.
