What do cells use hydrogen for, and where is it usually obtained?
a. Cells use hydrogen for energy production through its involvement in ATP synthesis.
b. Hydrogen is usually obtained from the diet, specifically from macronutrients such as carbohydrates and fats.
c. Hydrogen is a key component in cellular respiration, where it is used to generate a proton gradient for ATP production.
d. Cells can also obtain hydrogen from water through the process of splitting it into hydrogen and oxygen during photosynthesis.
