WebA gas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. It required 105 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 31 s for 1.0 L of O_2 O2 gas to effuse. Calculate the molar mass of the unknown gas.

Glucose v ATP One mole of glucose releases 2880 kJ of energy when burned completely in oxygen. Hydrolysis of one mole of ATP to ADP and phosphate releases 31 kJ of energy. Thus, the small WebThe Krebs Cycle (also known as the Citric acid cycle, or the Tricarboxylic acid cycle) is the next stage in Respiration. For every glucose molecule respired, the whole cycle takes place twice. So, for each turn of the Krebs Cycle, one ATP molecule is made. Each Acetyl CoA combines with an oxaloacetic acid to form a 6C citric acid.
