Question

Humans can harvest chemical energy not just from glucose but also from a variety of complex carbohydrates proteins, and fat molecules. Many of these molecules provide constant energy to sustain the body between meals. In order to generate ATP, these molecules follow different pathways through aerobic respiration. Examine the figure to see how fats, carbohydrates, and proteins enter the aerobic respiration pathway. Read the short paragraph following the figure and then answer the question that follows. FATS COMPLEX CARBOHYDRATES fatty acids glycerol amino acids PGAL Glycolysis 4 ATP (2 net) Cycle 2ATP NADH FADH2 Electron transfer 02 32 A Cancer cells grow very rapidly. As solid tumors grow, the cancer cells do not have access to enough oxygen. Without oxygen, electron transfer phosphorylation cannot occur. The Krebs cycle is also a limited occurrence in cancer cells. As a result, the rate of glycolysis is much higher in cancer cells than it is in normal cells because cancer cells rely much more heavily on this stage to generate enough ATP for their survival Based on this information and the pathways shown in the figure above, cancer patients may benefit from cutting which of the following molecules out of their diet? Check all that apply Proteins Complex carbohydrates

Explanation / Answer

Based on the given pathways and information complex carbohydrates yield high energy
compared to fats and proteins.
Both fats and proteins yeild less energy compared to comples carbohydrates.
Answers are three, all the fats, proteins and carbohydrates.
