Heat loss
Transport
6
Q
Functions of vitamins and minerals
A
Needed for normal function of enzymes and proteins
7
Q
What are enzymes
A
Biological catalysts
8
Q
How are enzymes effected by temp?
A
Higher the temp-faster rate of reaction,
After optimum temp the enzymes will be denatured
9
Q
How does PH effect enzymes
A
The higher the PH the faster the reaction
After the optimum PH the enzyme is denatured
