Lipids are made from two different molecules called fatty acids and glycerol. Because of this lipids are not polymers. We can show the possible reactions of any substance in a cell in a diagram.

These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose. Then, via respiration processes, cells use oxygen and glucose to synthesize energy ...

Oxygen does not react directly with molecules of pyruvate ... mitochondria to maximise ATP production by aerobic respiration. A muscle cell contains myofibrils, proteins that make the cell ...

A recent study published in Nature Communications suggests that stress may boost sperm respiration (energy production) and motility (movement) in both mice and men, with effects emerging several ...

but it's somewhere around 2.5 ATP molecules. That works out to 28–38 ATPs per glucose — again, a variable number, and never an integer (Silverstein 2005). Aerobic respiration is not ...
