The substances that are metabolized to yield energy that human cells use to perform work are the carbohydrates.
Answer: Option 1
Explanation:
The body generates ATP for all processes through the process called glycolysis cycle that takes place in the cytoplasm followed by the kerb cycle and the electron transport chain that takes place in the mitochondria.
The raw material for glycolysis is the glucose molecule thereby the entire energy production unit depends upon the raw material glucose. Since carbohydrates contain glucose they yield quick energy.
