Respiration: The act of inhaling and exhaling air in order to exchange oxygen for carbon dioxide.

What is respiration your answer?

Respiration is the 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 (energy).

What is respiration A level biology?

Respiration is the process, which occurs in living cells, that releases energy stored in organic molecules such as glucose. The energy released during respiration is used to synthesise molecules of ATP, which can be used as an immediate source of energy.

What is diffusion ks3?

Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out.

What is respiration with example?

The process by which organisms exchange gases, especially oxygen and carbon dioxide, with the environment. In air-breathing vertebrates, respiration takes place in the lungs. … Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air.

What is called respiration Class 10?

The process by which a living being utilizes the food to get energy is called respiration. Respiration is an oxidation reaction in which carbohydrate is oxidized to produce energy. Mitochondrion is the site of respiration and the energy released is stored in the form of ATP (Adenosine triphosphate).

What is respiration Class 9?

It is the process by which chemical energy stored in the food is released in the form of ATP along with carbon dioxide and water. Respiration begins with breathing, a combined process of inhaling oxygen and exhaling carbon dioxide.

What is respiration class 6th?

Respiration. Respiration is the chemical process in which food taken by an organism combines with oxygen to release energy. This energy is used by the organism to carry out its various life processes. Carbon dioxide and water are the other products of the process of respiration.

What is cellular respiration 7th grade?

Cellular respiration is a chemical process that enables organisms to convert food into energy. Plants carry out cellular respiration using the same chemical process that occurs in animals animals consume food only to get energy for the process of cellular respiration.

What happens respiration?

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). … Note the number of oxygen, carbon dioxide, and water molecules involved in each ‘turn’ of the process.

What is respiration in plants?

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. In the natural environment, plants produce their own food to survive.

What is respiration and types?

Respiration is the process of gas exchange between the air and an organism’s cells. Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. … Aerobic respiration is a cellular respiration that requires oxygen while anaerobic respiration does not.

What is respiration Class 11?

The process by which we release energy from organic compounds is known as Respiration. The released energy is then used for performing different physical activities. During respiration, the organic compounds are broken down internally into carbon dioxide and water.

What is the diffusion in biology?

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. The difference in the concentration of a substance between two areas is called the concentration gradient .

What is diffusion in biology simple definition?

diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. ion diffusion across a semipermeable membrane.

What is diffusion in biology class 9?

Diffusion can be described as the process of movement of molecules from a region of higher concentration to a region of lower concentration allowing the entry and exit of substances in and out of cells.

How is ATP formed in respiration?

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

What is energy according to biology?

Specifically, energy is defined as the ability to do work – which, for biology purposes, can be thought of as the ability to cause some kind of change. … Energy is never lost, but it can be converted from one of these forms to another.

What is ATP a level biology?

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule.

What is respiration in Ncert?

The breaking of the C-C bonds of complex compounds through oxidation within the cells, leading to release of considerable amount of energy is called respiration. The compounds that are oxidised during this process are known as respiratory substrates.

What is respiration Class 10 Brainly?

Answer: The process of releasing energy from food is called respiration. The process of respiration involves taking in oxygen (of air) into the cells, using it for releasing energy by burning food, and then eliminating the waste products (carbon dioxide and water) from the body.

What is respiration explain in chemistry?

Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions.

What is respiratory system Class 5?

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

What is cellular respiration and fermentation?

Cellular respiration uses oxygen in the chemical reaction that releases energy from food. Fermentation occurs in an anaerobic or oxygen-depleted environment. Because fermentation doesn’t use oxygen, the sugar molecule doesn’t break down completely and so releases less energy.

How do you explain 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.
