<u>Answer</u>:
A total of 32 ATP molecules per glucose molecule is generated in cellular respiration and glycolysis. In substrate-level phosphorylation, ATP is generated from the coupled reactions whereas in oxidative phosphorylation ATP is formed by using the oxidized NADH and FADH cofactors. The energy for oxidative phosphorylation comes from the movement of proton to the matrix of mitochondria through ATP synthase.
<u>Explanation</u>:
Each molecule of glucose utilizes 2 ATP molecules and breaks down into 2 pyruvate molecules and generates 4 ATP from substrate-level phosphorylation and 2 molecules of NADH.
Pyruvate converts into acetyl Co-A and produces 2 molecules of NADH. In citric acid cycle, the 2 molecules of acetyl Co-A produces 2 molecules of GTP/ATP, 6 molecules of NADH, 2 molecules of FADH2.
In oxidative phosphorylation 1 molecule of NADH contributes to the production of 2.5ATP, FADH2 gives 1.5ATP. Hence the total production of ATP is 4 + 2 + 25 + 3 = 34 – 2 ATP (used early in glycolysis) = 32 ATP (net ATP production).

Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
The rate of appearance of water to the initial rate of the disappearance of oxygen is 2:1.
Formation of H2O.
2 H2 + O2 --> 2 H2O
From the equation,
we can conclude that 2 moles of water appear from 1 mole of O2 .
Water (H2O) is an inorganic, transparent, tasteless, odorless, and almost colorless chemical substance that is the major ingredient of the Earth's hydrosphere as well as the fluids of all known living species. Despite not providing food, energy, or organic micronutrients, it is essential for all known forms of life.
Its chemical formula, H2O, reveals that each of its molecules is made up of one oxygen and two hydrogen atoms that are linked together by covalent bonds. The hydrogen atoms are at an angle of 104.45° to the oxygen atom.
