When most proteins, fats, and carbohydrates are digested (broken down) completely outside the cell, they are converted to end products. What happens to these smaller subcomponents?

Question

Question 4 options:

The smaller components will all contain atoms of carbon, hydrogen, oxygen, and nitrogen.

The smaller components can then pass through cell membranes.

The smaller components are joined back together outside the cell to form components the cell needs.

The smaller components would have long chains of amino acids and fatty acids.

Answer 1

The correct answer is:

The smaller components can then pass through cell membranes.

After digestion, proteins, fats, and carbohydrates are broken down into smaller subcomponents such as amino acids, fatty acids, and simple sugars (monosaccharides). These smaller components can then pass through the cell membranes and be used by the cells for various metabolic processes.
