Cellular Respiration Flashcards
What is cellular respiration?
Cellular respiration is converting glucose to ATP (the unit of energy in a cell)
What is the word equation for cellular respiration?
Glucose + Oxygen = ATP + Carbon Dioxide + Heat + water
Why do cells need cellular respiration?
Because they need energy to carry put the process of the cell
How does temperature effect cellular respiration?
as temperature increases the rate of cellular respiration increases.
How does the amount of oxygen effect the rate of cellular respiration?
The increase of oxygen will increase the rate of cellular respiration but this increase is limited by the amount of glucose and the amount of enzymes present.
How does the amount of glucose affect the rate of cellular respiration?
The increase of glucose will increase the rate of cellular respiration but this increase is limited by the amount of oxygen and the amount of enzymes present.
How does pH affect the rate of cellular respiration?
The enzymes that catalyse the reaction have an optimum pH and outside of that optimum pH the rate of reaction will decrease until it reaches the outside of the pH range and outside that range the enzymes denature.
What is the difference between aerobic and anaerobic respiration?
aerobic is with oxygen and anaerobic is without.
What is mitochondria?
The site of cellular respiration
What is the structure of mitochondria?
The crista are the folds in the inner membrane which provide a large surface area for the reaction to happen, and the matrix is the fluid that contains enzymes which helps speed up the reaction.
Why do different parts of the body contain different amounts mitochondria?
Different parts of the body have different energy demands e.g. bone cells require less ATP - less mitochondria whereas the heart requires a lot of ATP - large amounts of mitochondria.
