Explanation

Glycolysis produces a net gain of 2 ATP molecules (4 produced – 2 used) per glucose molecule.

It also generates 2 NADH molecules, which can be used in oxidative phosphorylation for further ATP production.

Explanation

Protoplasm includes the plasma membrane and all the contents within it, i.e., the cytoplasm + nucleus.

These structures help in both locomotion and capturing food (phagocytosis).

Explanation

 Human tissues, particularly in organs like the brain and kidneys, can contain approximately 85% water.

The exact percentage varies by tissue type, but many, especially soft tissues, are largely composed of water.

Explanation
