Question

Out of 36 ATP molecules produced per glucose molecule during respiration
A) 2 are produced outside glycolysis and 34 during respiratory chain
B) 2 are produced outside mitochondria and 34 inside mitochondria
C) 2 during glycolysis and 34 during Krebs cycle
D) All are formed inside mitochondria

Answer 1

Hint: ATP, or adenosine triphosphate, is a molecule that transports energy inside cells. It is the key energy currency of the cell, and it is an end result of the processes of photophosphorylation (adding a phosphate group to a molecule utilising energy from light), cellular respiration, and fermentation.

Complete answer:
Glycolysis is a series of reactions that break glucose into two three-carbon molecules called pyruvates and extract energy from it. Glycolysis is an ancient metabolic pathway that originated many years ago and is present in the vast majority of living organisms today.

Cellular respiration is a series of metabolic reactions and processes that occur within organisms' cells to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products.

Respiration involves catabolic reactions, which break large molecules into smaller ones, releasing energy when weak high-energy bonds, such as those found in molecular oxygen are replaced by stronger bonds in the products.

2 ATP is generated by glycolysis in the cytoplasm, and 34 ATP is produced by other cellular respiration processes in the mitochondria. '2 are produced outside mitochondria and 34 are produced within mitochondria.’

Therefore the correct answer is option ‘B’.

Note: Adenosine triphosphate (ATP) is an energy-carrying molecule present in all living organisms' cells. ATP is a molecule that absorbs chemical energy from the breakdown of food molecules and then releases it to power other cellular processes.
