B1.3.2 - Aerobic Respiration Flashcards
What is respiration?
The chemical reaction that occurs providing a constant supply of energy to the body
What is aerobic respiration?
Where glucose reacts with oxygen
What is the word equation for aerobic respiration?
Glucose + Oxygen —> Carbon Dioxide + Water
What is ATP?
The energy produced in respiration
What is the energy produced used for? State 3.
1) Synthesise larger molecules into smaller ones to make new cell material
2) Movement, contract muscle cells to make organism move
3) Stay warm and keep the body at a constant temperature
Where does respiration occur?
Takes place in the mitochondria
Why does the number of mitochondria very in different parts of the body?
It depends on how active the site it. If one place is used more, that place will have more mitochondria. For example, muscles are used frequently for movement so they have a large number of mitochondria. Many chemical reactions occur in the liver, so more mitochondria there too.
What kind of reaction is respiration?
An exothermic reaction, heat/energy is given OUT to surroundings
