Which energy source is consumed in greater quantities during stress?

Which energy source is consumed in greater quantities during stress?

• A. Glucose
• B. Lipids
• C. Amino acids
• D. Nucleotides

Answer: (A)

When the body faces stress, energy needs rise rapidly, and glucose becomes the main fuel because it can be turned into ATP quickly to power cells, especially the brain and muscles. Stress hormones mess you releasing glucose from the liver and promoting gluconeogenesis, so more glucose is available and used right away. Lipids provide a large energy reserve but are tapped more in longer, sustained activity rather than the immediate surge during stress. Amino acids can be used for energy or to make glucose later on, but they aren’t the primary rapid fuel in acute stress. Nucleotides aren’t a primary energy source in this context; the body relies on glucose to meet the sudden demand.
