Metabolism

Reaction in which larger molecules are created from smaller ones.

This substance is the preferred source of energy for metabolism.

Anaerobic respiration occurs in mitochondria.

Extra fuel in any of the 3 forms (glucose, fat, amino acids) will be converted to fat if not utilized.

If you run 100 metres sprint, your body will use the lactic energy pathway.

The respiratory and cardiovascular systems participate in the aerobic energy pathway.

The 3 energy pathways cannot be functioning simultaneously.

When lactic acid enters the blood stream, the pH in the cell goes up and the enzymes stop working.

O2 must be present for the Citric Acid Cycle (Krebb's cycle) to be able to start.

ATP and ADP molecules can shuffle back and forth between energy-releasing and energy-utilizing reactions of the cell.

Gram for gram, fat contains less chemical energy than CHO or protein.
