Question

20) chain and transfer their high energy electrons to the electron transport A. NAD, FAD B. ATP, NADH C. NADH, FADH2 D. ATP, FADH2 21) True/False. Energy can only be harvested from simple sugars that we consume. Other foods such as fats and proteins cannot be used as an energy source. 22) Name 3 functions of a cell membrane (there are more than three functions of a cell membrane), o protects the cel achy ots?loor, , 23) Describe two functions of membrane proteins Chere are more than two funciogns of nd oul membrane proteins). D tromp, 24) Membrane transport that requires energy is called transport. A) Diffusion B) Osmosis ctive transport ) Passive transport 25) If the amount of Na+ is less concentrated on the INSIDE of the cell than the OUTSIDE of the cell, the solution the cell is in is said to be: A) Isotonic B) Hypertonic C) Hypotonic 26) Cell products are excreted through the process of: A) Endocytosis B) Pinocytosis C) Exocytosis D) Trancytosis

Explanation / Answer

20. The correct option is C. NADH and FADH2.

NADH and FADH2 transfer high-energy electrons to the electron transport chain.

21. The correct option is FALSE.

The statement is false because energy can also be harvested from proteins and fats.

22. Cell membrane is a thin, elastic, semipermeable membrane which serves as a boundary for the Cytoplasm.

24) Functions of membrane proteins:
