What Is Cellular Respiration And Why It Is Needed?

by | Last updated on January 24, 2024

, , , ,

The main function of cellular respiration is

to synthesize biochemical energy

. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes.

What is cellular respiration short answer?

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.

Why do cells need cellular respiration?

Cells do cellular respiration

to extract energy from the bonds of glucose and other food molecules

. Cells can store the extracted energy in the form of ATP (adenosine triphosphate).

What is cellular respiration explained for kids?

Cellular respiration is the process by which organisms

use oxygen to break down food molecules to get chemical energy for cell functions

. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.

Where does cellular respiration happen?

While most aerobic respiration (with oxygen) takes place in

the cell’s mitochondria

, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

What is the main purpose of cellular?

They provide structure for the body,

take in nutrients from food, convert those nutrients into energy

, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.

What is the best definition of cellular respiration?

Cellular respiration, the process by

which organisms combine oxygen with foodstuff molecules

, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

What is an example of cellular respiration?

Oxygen is used in cellular respiration. … For example, the

monosaccharide glucose

, (the most basic form of carbohydrate) can be combined with oxygen. The high energy electrons that are found in the glucose are transferred to the oxygen and potential energy is released. The energy is stored in the form of ATP.

How does cellular respiration work in humans?

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell

uses oxygen to break down sugar

. … When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.

What are 3 facts about cellular respiration?

Cellular respiration is

what cells do to break up sugars to get energy they can use

. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. … Aerobic respiration, the process that does use oxygen, produces much more energy and doesn’t produce lactic acid.

Who uses cellular respiration?


Organisms from all kingdoms of life

, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.

What is respiration example?

Respiration is taking a breath or the act of breathing. An example of respiration is

inhaling and exhaling air

. The action or process by which an organism without lungs, such as a fish or plant, exchanges gases with its environment. … Respiration in green plants occurs during photosynthesis.

Does cellular respiration happen in humans?

Respiration happens in the cells of plants, animals and humans,

mainly inside mitochondria

, which are located in a cell’s cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

What are the 3 stages of cellular respiration and where do they occur?

Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages:

glycolysis, the Krebs cycle, and electron transport.

Which substances are needed for cellular respiration?


Oxygen and glucose

are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

What are the 2 types of cellular respiration?

There are two main types of cellular respiration—

aerobic respiration and anaerobic respiration

. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O

2

) is required to create ATP.
