Question

2. Respiration is a chemical reaction.
(a) Where does it take place?
(c) Why is it important for living cells?
(b) What type of chemical reaction is it?​

Answer 1

Answer:

Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).

a)The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.

c)All organisms respire to release energy to fuel their living processes. The respiration can be aerobic , which uses glucose and oxygen, or anaerobic which uses only glucose.

b)exergonic reactions
