What is respiration explain?

1 : the act or process of breathing : the inhaling of oxygen and the exhaling of carbon dioxide. 2 : the process by which cells use oxygen to break down sugar and obtain energy. respiration.

What are different types of respiration?

Respiration is of two types- Aerobic respiration: Occurs in the presence of oxygen Anaerobic respiration: Occurs in the absence of oxygen

• Aerobic respiration: Occurs in the presence of oxygen.
• Anaerobic respiration: Occurs in the absence of oxygen.

What are the 4 steps of respiration?

There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.

What is respiration for 6th class?

Respiration is the process that all living things go through to create the energy they need to live. This happens in the cells so it is also called cellular respiration. It usually involves exchanging two gases—oxygen and carbon dioxide. The cells take in oxygen and release carbon dioxide.

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. The process of inhaling and exhaling; breathing, breath.

What are two main types of respiration?

The Presence of Oxygen There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic.

What is the first step in respiration?

glycolysis
The first stage of cellular respiration, called glycolysis , takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.

What are two main processes of respiration?

Inhalation – Inhalation (also known as inspiration) happens when oxygen from the air enters the lungs. Exhalation – Exhalation (or expiration) is the flow of the breath out of an organism.

What is respiration Why is it important class 6?

Respiration provides cells with oxygen and expels toxic carbon dioxide. Some energy released by respiration is also in the form of heat. This heat energy contributes significantly in the warm-blooded animals towards the body.

What is plant respiration definition?

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. As with photosynthesis, plants get oxygen from the air through the stomata.

What is an example of respiration?

Act or process of respiring; breathing; inhaling and exhaling air. 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.

What are the differences between fermentation and cellular respiration?

Fermentation differs from cellular respiration in a way that it uses organic compounds such as carbohydrates as (endogenous) electron acceptors instead of molecular oxygen (which is an exogenous electron acceptor in cellular respiration).

What is the equation for cellular respiration?

Cellular respiration is the process by which organisms convert the biochemical energy of nutrients into ATP. This process breaks down glucose into six carbon dioxide molecules and twelve water molecules. The overall chemical equation for aerobic respiration is C6H12O6 + 6O2 + 6H2O →…

What is the chemical reaction for respiration?

The reactants in the process of cellular respiration are sugar and oxygen. They react to produce carbon dioxide, water, and energy. The chemical equation is as follows: C 6 H 12 O 6 + O 2 → CO 2 + H 2 O + energy
