Answer:
The correct answer is D. maintain membrane fluidity through its disruption of fatty acid packing.
Explanation:
<u>Cholesterol</u> is a steroid lipid and is a constituent of biological membranes. It regulates the <em>fluidity</em> of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is <em>D. maintain membrane fluidity through its disruption of fatty acid packing.</em>
I think A is the answer it makes the most sense to me
<span>3. Cells use glucose to store large amounts of energy for long period of time.
In contrast, ATP is used to </span>store smaller amounts of energy that will be used in the next few seconds.<span>
A glucose molecule can store more than 90 times the energy of a ATP molecules.
