a. Yes! Three grams of chlorophyll is insufficient to produce measurable amounts of energy.
b. No; chlorophyll in leafy greens and sports drinks continues photosynthesis after ingestion.
c. Yes! Sunlight will have no effect on the amount of energy derived from digested chlorophyll.
d. Yes! Humans cannot metabolize the carbohydrates produced by photosynthesis.
c. Yes! Sunlight will have no effect on the amount of energy derived from digested chlorophyll.
