photosynthesis? How many ATPs are produced upon
complete oxidation of one molecule of glucose by
aerobic respiration?​

Answer 1

Explanation:

respiration is a catabolic process

38 ATP

Answer 2

Question :-

Which of these is a catabolic process - respiration or photosynthesis?

Answer :-

Respiration is the catabolic process.

Catabolic process - It includes metabolic processes by whoch larger molecules are broken down into simpler molecules.

Respiration is the process in which oxygen oxidizes food molecules present in the body cells and energy is released in the form of ATP.

$\sf Food + oxygen \xrightarrow{Oxidation} CO_2 + H_2O + Energy \: (ATP)$

Question :-

How many ATPs are produced upon complete oxidation of one molecule of glucose by aerobic respiration?

Answer :-

Aerobic respiration is the oxidation of food in the presence of oxygen.

Equation for aerobic respiration -

$\sf Food \xrightarrow{Glycolsis} Pyruvic\: acid \xrightarrow{in \:presence \:of\:O_2} 6H_2O + 6CO_2 + 38 ATP$

So, 38 ATP molecules are produced upon complete oxidation of one molecule of glucose by aerobic respiration.
