What are some ways individual cells in an organism use energy?

Cells use energy in order to grow, regulate metabolism and reproduce. This energy is obtained from a source such as food molecules or light from the sun, and through processes like glycolysis, the citric acid cycle and oxidative phosphorylation, an energy-rich molecule is then created. The cell can then use the energy in the protein molecule to help it function. brainliest?

d. making up measurements to record.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
