Ribosomes and mitochondria
Answer: E. All of the above are present in liver cells
Cheese is composed of fats and proteins. On reaching the stomach gastric juice is produced, which contains pepsin that acts on proteins to form dipeptides. In the duodenum, enzymes trypsin and chymotrypsin released from the pancrease acts on dipeptides to produce peptides. Bile juice from the bile acts on fats to form small fats droplets a process called emulsification. In the small intestines enzyme peptidase acts on peptides to form amino acids, while enzyme lipase acts on fat droplets to produce fatty acids and glycerol. Amino acids, fatty acids and glycerol are then absorbed into the blood stream.

Answer:
1. Part A: No
2. Part B: Yes
3: Part C : Yes
4: Part D : No
Explanation:
1) Part A: Facilitated diffusion of glucose into a muscle cell:
No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose
2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:
Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.
3) Part C: Uptake of potassium ions by red blood cells:
Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.
4) Part D: Active uptake of lactose by the bacteria in your intestine
No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.
