What is cellular respiration in simple terms?

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 cellular respiration and why is it important?

Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.

How do you explain cellular respiration to a child?

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.

Why is it called cellular respiration?

Cellular respiration works either in the presence or absence of oxygen. But essentially, the process is called cellular respiration because the cell seems to “respire” in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product).

What happens during cellular respiration?

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

What is an example of cellular respiration?

An example of cellular respiration in plants is the use of photoautotrophic processes to obtain the glucose needed for cellular respiration. This means that plants can use the light energy they acquire from the sun to yield glucose and oxygen.

What are 3 facts about cellular respiration?

There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.

Where does cellular respiration occur?

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.

Do humans use cellular respiration?

Cellular respiration is a metabolic pathway that converts nutrients into energy (ATP) that organisms need to live. For aerobic cellular respiration to occur, oxygen has to be present. Humans and other animals obtain oxygen for cellular respiration through breathing.

What is cellular respiration also called?

Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.

Which of the following best defines cellular respiration?

Which of the following is the best definition of cell respiration? A controlled release of energy, in the form of ATP, from organic compounds in cells.

What is the main product of cellular respiration?

The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

What is respiration process?

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

What are the 4 steps of cellular respiration?

  • 1st- Glycolosis. Splitting sugars in cytoplasm, energy investment phase -> 2 ATP molecules combine with glucose molecule.
  • 2nd- Oxidation. Pyruvates moving into mitochondria, through oxidation pyruvates broken into water.
  • 3rd- Krebs Cycle/Citric Acid Cycle.
  • 4th- Electron Transport Chain.

How does cellular respiration affect the body?

Cellular respiration is a set of metabolic reactions, which occurs within the cells of individuals. During this biological process, energy is produced, which is used for various metabolic activities in the cells. Without respiration: Our body cannot produce energy for cellular metabolism.

What would happen without cellular respiration?

Without the process of cellular respiration, there is no gaseous exchange and the cells, tissue and other organs die due to the lack of oxygen and by the accumulation of carbon dioxide within the cells and tissues.

What organs are involved in cellular respiration?

Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes. During respiration, glycolysis occurs in the cytoplasm of the cell.

What is required for cellular respiration?

Cellular respiration is a set of metabolic reactions, which occurs inside the living cells. Glucose and oxygen are the reactants of this process, whereas, carbon dioxide, water, and energy (ATP) are the by-products.

What’s the role of oxygen in cellular respiration?

Oxygen serves as a final electron acceptor of the electron transport chain in cellular respiration assisting the movement of electrons down a chain, resulting in the production of adenosine triphosphate (ATP). Oxygen combines with electrons and hydrogen ions to produce water. Hence the importance.

What happens to energy during cellular respiration?

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

What type of reaction is cellular respiration?

Respiration releases chemical energy stored in sugars, making it an exothermic reaction.

What is the main source of energy for cellular respiration?

The primary fuel for cellular respiration is a molecule of glucose, which is used to make energy. In the cellular world, energy is a charged molecule with three phosphate groups called adenosine triphosphate (ATP).

Can we live without cellular respiration?

No. Cellular respiration is essential for life. It occurs continuously throughout life.

Why is ATP Important?

ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

How ATP is formed?

ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.
