What is a substrate ?
The reactant molecule that enzymes act upon to facilitate a chemical reaction.
What is enzyme-substrate complex ?
The intermediate formed when a substrate binds to an enzymes active site.
How does temperature affect enzyme activity ?
Optimal temperature enhances enzyme reaction rates, while extreme temperatures can denature enzymes.
What is denaturation in enzymes ?
The process where enzymes lose their functional shape due to extreme conditions.
Which enzyme breaks down starch ? What is it broken into ?
Starch is broken down by the enzyme amylase into maltose molecules.
