An%20arrow%20points%20from%20food%20to%20glucose%2C%20and%20a%20second%20arrow%20points%20from%20food%20to%20amino%20acids%2C%20vitamins%2C%20and%20other%20nutrients.%20One%20arrow%20from%20glucose%20joins%20with%20oxygen%20to%20point%20to%20carbon%20dioxide%20plus%20water%20plus%20energy.%20A%20second%20arrow%20points%20from%20glucose%20to%20an%20empty%20box.%20An%20arrow%20from%20amino%20acids%2C%20vitamins%2C%20and%20other%20nutrients%20also%20points%20to%20the%20empty%20box.
What phrase would be most useful for Kyle to write in the empty box?

A.
blood or other body fluids
B.
wastes that are removed from the organism
C.
molecules that store energy or support growth
D.
chromosomes, genes, and DNA

Answer 1

C.

Glucose and amino acids are used to build larger molecules (like glycogen and fats for energy storage, and proteins for growth/structure), so "molecules that store energy or support growth" fits.
