Question

choose the molecule or process that is described by each phrase. lactic acid is a byproduct of this process: anaerobic respiration. complete this is the energy stored as adipose tissue: lipid. complete this is the process best utilized for brisk walking and jogging: aerobic respiration. complete this can be used for energy, but should be a last resort: glycogen lipid protein

Explanation:

• Glycogen: It is a readily available energy source stored in the liver and muscles. When glucose levels are low, glycogen is broken down into glucose to provide energy.
• Lipid: Lipids, especially triglycerides stored as adipose tissue, are a concentrated form of energy. They provide a large amount of energy when metabolized.
• Protein: Proteins are mainly used for building and repairing tissues, enzymes, and hormones. While they can be used for energy in extreme cases (like prolonged starvation when other energy sources are depleted), it is not their primary function and using them for energy can have negative impacts on the body's structure and function.

Answer:

protein
