What is respiration for ks3?
Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).
What is respiration GCSE definition?
Respiration is a chemical process that occurs in every cell of an organism. Energy is released from the breakdown of food (glucose). Respiration requires oxygen to fully break down. food in the form of glucose into water, carbon. dioxide and energy, as shown in the word equation.
What is cellular respiration BBC Bitesize?
All organisms respire in order to release energy to fuel their living processes. The respiration can be aerobic, which uses glucose and oxygen, or anaerobic which uses only glucose. Respiration must happen all of the time so that the organism can survive.
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 meant by respiration Class 7?
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 food, and then eliminating the waste products (carbon dioxide and water) from the body. This energy is used by the living organism.
What is diffusion Bitesize?
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. Diffusion is an important process for living things – it is how substances move in and out of cells.
What is respiration and how does respiration work?
Respiration involves chemical reactions that break down nutrient molecules in living cells to release energy. Aerobic respiration needs oxygen. It is the release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of oxygen: Aerobic respiration happens all the time in animals and plants.
What is the chemical reaction of aerobic respiration?
The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps. Where next? What is aerobic respiration?
How does glucose break down in anaerobic respiration?
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
Where does aerobic respiration occur most of the time?
Aerobic respiration occurs in the presence of oxygen and in most cells most of the time. Anaerobic respiration occurs without oxygen and much less frequently than aerobic respiration. Human bodies…
