Question

What Is Respiration? How Does It Occur?

Answer 1

Hi,
the meaning is
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.(how does it occurs).
Respiration can be aerobic (uses oxygen) or anaerobic (does not use oxygen). Aerobic respiration takes place continuously in both plants and animals. ... Aerobic respiration releases lots of energy from each glucose molecule by breaking it down completely into carbon dioxide and water.
I hope you might have got your answer.
PLEASE MARK IT AS BRAINLIST IF YOU LIKED IT..

Answer 2

$\Huge{\textbf{Answer:}}$

→ $\blue{\textbf{What is Respiration?}}$

• 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 or anaerobic.

• Aerobic respiration takes place continuously in both plants and animals.

→ $\blue{\textbf{How Does It Occurs?}}$

• It occurs through a process known as cellular respiration.

• It is of 2 types:

→ $\green{\textbf{Aerobic Respiration:}}$

• 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.

→ $\green{\textbf{Anaerobic Respiration:}}$

• 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.
