The Role Of Enzymes Flashcards
1
Q
What are enzymes?
A
-biological catalysts - speed up the rate of chemical reactions without being used up or undergoing permanent change
-alternative reaction pathway with lower AE
2
Q
What are intracellular enzymes?
A
-enzymes are produced and function inside the cell
3
Q
What are extracellular enzymes?
A
-enzymes are secreted by cells and catalyse reactions outside of cells
4
Q
Examples of intracellular
A
-DNA helicase, DNA polymerase + catalase
5
Q
Examples of extracellular
A
-amylase, trypsin, protease + lipase
6
Q
Enzyme structure
A
-active site shape is determined by sequence of amino acids
-tertiary structure - altered by changes in temp + pH
