One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy in one of two ways.
Two pyruvate
Photosynthesis<span> makes the glucose that is used in </span>cellular respiration<span> to make ATP. The glucose is then turned back </span>into <span>carbon dioxide, which is used in </span>photosynthesis<span>. While water is broken down to form oxygen </span>during photosynthesis, in cellular respiration<span> oxygen is combined </span>with<span> hydrogen to form water.

The independent variable is a variable that can be stood alone. So therefore, the independent variable would be how long it takes to parachute.
