Which are the cholesterol esters that enter cells through the receptor-mediated endocytosis of lipoproteins hydrolyzed?

Here are the answers to the questions:

1. Which are the cholesterol esters that enter cells through the receptor-mediated endocytosis of lipoproteins hydrolyzed?
Cholesterol esters, once inside the cell via receptor-mediated endocytosis, are delivered to the lysosomes where they are hydrolyzed by lysosomal acid lipases.

• B. Lysosomes

2. The power house of the cell is
Mitochondria are responsible for generating most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy, through cellular respiration.

• C. Mitochondria

3. Fatty acids can be transported into and out of cell membrane by
Fatty acids are small, lipid-soluble molecules that can pass directly through the lipid bilayer of the cell membrane down their concentration gradient, a process known as simple diffusion.

• C. Diffusion

4. A lipid bilayer is permeable to
The lipid bilayer is selectively permeable. Small, uncharged molecules like urea can pass through it, while larger polar molecules (like fructose, glucose) and ions (like potassium) generally cannot without specific transporters.

• A. Urea

5. The average pH of Urine is
The normal pH range for human urine is typically between 4.5 and 8.0. The average pH is generally considered to be slightly acidic.

• B. 6.0

6. The surface tension in Intestinal lumen between fat droplets and aqueous medium is decreased by
Bile salts are amphipathic molecules that emulsify fats in the small intestine, reducing the surface tension between fat droplets and the aqueous intestinal contents, allowing for better digestion and absorption.

• A. Bile Salts

7. The following factors stimulate filtration at the glomerulus except:
The options for this question are largely unreadable due to the image quality. Therefore, I cannot provide an accurate answer.
