1.11 - Rate Calculations for Enzyme Activity Flashcards
(8 cards)
What are rate calculations used for in Biology?
Rate calculations are used to determine how fast an enzyme is working (the rate of reaction).
What is the formula for rate calculation?
Rate = Change / Time
What does ‘Change’ refer to in the rate calculation?
‘Change’ refers to the change in the substance being measured, such as the enzyme.
What does ‘Time’ refer to in the rate calculation?
‘Time’ refers to the time taken for the change to occur.
What are proteases?
Proteases are a type of enzyme used to break down proteins.
How do you calculate the rate of reaction for proteases?
Rate = Change / Time
Example: If 5g of protein is added and it takes 30 minutes to convert all the protein, then Rate = 5g / 30 minutes = 5g / 0.5 hours.
What is the rate of enzyme catalysis?
10g / hour
This rate may change depending on temperature, pH, and substrate concentration.
What factors can affect the rate of enzyme catalysis?
Temperature, pH, and substrate concentration.
