Cell metabolism is a series of enzyme catalysed reactions that build up or break down molecules. Enzymes are affected by temperature and pH. Aerobic and anaerobic respiration produce ATP and heat.
Enzymes are made from which biochemical molecule?
The substrate fits into which part of the enzyme?
As temperature increases what happens to the rate of enzyme action ?
Stays the same
What is the enzyme called if the active site has changed shape due to high temperatures or extreme changes in pH?
What is the optimum temperature for enzymes found in the human body?
The long chain carbohydrate starch is broken down by what type of enzyme?
Benedict’s reagent indicates the presence of glucose in food. What is the correct order of colour changes if glucose is present?
Which of these substances is released during anaerobic respiration in humans?
Which of these is a molecule produced during respiration?
In anaerobic respiration, less energy is released from food for what reason?
Glucose is not used as the respiratory substrate
Glucose has not been broken down completely
There is no carbon dioxide available
