A special protein carrier in plasma membrane is:
Correct answer: C. Permease
- A. Catalase
- B. Lipase
- C. Permease
- D. Arginase
Explanation
The correct answer is Permease, which is a protein carrier in the plasma membrane. Permease functions by specifically binding to molecules on one side of the membrane and facilitating their movement across the membrane through a conformational change. This is essential for processes like nutrient uptake and waste removal.Other options like Catalase, Lipase, and Arginase are enzymes with roles unrelated to membrane transport. Catalase breaks down hydrogen peroxide, Lipase digests lipids, and Arginase participates in the urea cycle, making them incorrect choices for this question.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
