Question

small intestine. these smaller molecules are able to cross the cell membrane and er once inside a cell, fatty acids and glycerol are recombined into a triglyceride. trigly then stored in fat tissue until they are needed for energy. stearin, a triglyceride select the true statements. triglycerides are stored until they are needed for energy. triglycerides travel across cell membranes. in cells, fatty acid and glycerol molecules are combined to make triglycerides.

Explanation:

1. For "Triglycerides are stored until they are needed for energy": The text says "Triglyceride... then stored in fat tissue until they are needed for energy", so this is true.
2. For "Triglycerides travel across cell membranes": The text states "These smaller molecules (from digestion of triglycerides) are able to cross the cell membrane", not the triglycerides themselves, so this is false (the original selection here is incorrect).
3. For "In cells, fatty acid and glycerol molecules are combined to make triglycerides": The text says "Once inside a cell, fatty acids and glycerol are recombined into a triglyceride", so this is true.

Answer:

• Triglycerides are stored until they are needed for energy.
• In cells, fatty acid and glycerol molecules are combined to make triglycerides.
