Question

1. What is respiration? How does it occur?​

Answer 1

Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).

Answer 2

Answer:

hey dear....

Here is your answer

What is respiration ?

All living organisms need a constant supply of energy.

Respiration is the process of releasing energy through

the breakdown of nutrients such as glucose.

Respiration can be aerobic (uses oxygen) or anaerobic

(does not use oxygen). Aerobic respiration takes place

continuously in both plants and animals.

how does it occur ?

It occurs through a process known as cellular respiration.

It is of 2 types:

• Aerobic respiration : Aerobic respiration uses oxygen to

break down glucose.

• Aerobic respiration can be described as the process

of releasing energy through the oxidation of glucose

molecules.

Aerobic respiration releases lots of energy from each

glucose molecule by breaking it down completely into

carbon dioxide and water.

Anaerobic respiration : Anaerobic respiration takes place

without oxygen.

Anaerobic respiration is the incomplete breakdown of

glucose. This process releases much less energy per

glucose molecule than aerobic respiration and produces

lactic acid.

Anaerobic respiration occurs when cells have

insufficient oxygen for aerobic respiration to occur, for

example, during strenuous exercise.
