Avagadro's number is the amount of molecules in a mole. This is 6.022x10^23 molecules. There will be 6.022x10^20 molecules in a millimole and 6.022x10^14 in a nanomole. Therefore, the difference between these is how many molecules there are in the difference. This gives you approx 6.021994x10^20 molecules. This is limited by the amount of significant figures for avagadros number that I know of.

A brain cell is made of many molecules.
It has 2 ATP molecules.
Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
On average, a cell can produce around 10 million ATP molecules per second through cellular respiration. However, this number can vary depending on factors such as cell type, energy demands, and environmental conditions.

Approximately 19 ATP molecules can be generated from the metabolism of a molecule of glycerol through the process of glycolysis and the citric acid cycle.
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
If cellular respiration begins with two molecules of glucose, a total of about 76 molecules of ATP can be generated through the process of glycolysis, the citric acid cycle, and oxidative phosphorylation. This is because each molecule of glucose yields approximately 38 molecules of ATP through the complete process of cellular respiration.
No, a molecule is smaller than a cell. A molecule is made up of atoms, while a cell is a basic structural and functional unit of living organisms. Cells can contain many molecules within them.

The amount of ATP used by a human cell per second can vary depending on factors such as cell type and metabolic activity. However, on average, a human cell can use up to 1 billion molecules of ATP per second to support various cellular processes such as metabolism, signaling, and movement.
One hemoglobin molecule in a red blood cell can bind up to four oxygen molecules. Therefore, one blood cell could potentially carry up to four oxygen molecules at a time.
