Answer 1

Answer:

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

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 : -

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