Question

defination of cellular respiration​

Answer 1

Answer:

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP.

Explanation:

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP.

Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Respiration is the process which involves the chemical break down of glucose to release ATP (energy) for the body. C02 is a biproduct which is expelled through the lungs.

There are two types of respiration: -

• Aerobic respiration - This is the breakdown of Glucose in the abundance of oxygen this is the more efficent of the two processes and creates the most amount of energy. 52 molecules of ATP.

CHEMICAL FORMULA for Aerobic respiration : -

• $\bf \: C_6H_{12}O_6 + 6O_2 \: \rightarrow \: 6CO_2 + 6H_2O + Energy$

• Anaerobic respiration - This is the breakdown of Glucose in the absence of oxygen. This is not an efficient process, only 2 molecues of ATP are produced and a biproduct is lactic acid. which is what causes aches and cramps in muscles after excercise.

CHEMICAL FORMULA for Anearobic respiration : -

• $\bf \ C_6H_{12}O_6 \ \rightarrow \ 2C_3H_6O_3 + 2 ATP$
