What are Enzymes?
They are proteinous "biological catalysts" "speeding up the chemical reaction".
2
New cards
What is the role of Amylase?
It aids "digestion of starch".
3
New cards
What is the role of Cellulase?
It aids "digestion of cellulose".
4
New cards
What is the role of Protease?
It aids "digestion proteins".
5
New cards
What are the factors affecting enzyme reaction?
Factors affecting are "pH - Temperature - Enzyme and Substrate concentration".
6
New cards
What is the effect of pH on enzyme activity?
As pH moves away from the pH scale the "rate of reaction decreases". A change in pH causes the shape of active site to change.
7
New cards
What is the effect of temperature on enzyme activity?
It works "best at higher temperature" but at a "temperature above optimum temperature the enzyme denatures".
8
New cards
What is the effect of enzyme and substrate concentration on enzyme activity?
As the "substrate concentration increases the rate of reaction increases" to an initial point to make reaction constant + "Increase in enzyme concentration increases rate of enzyme reaction".
