34
Q

What is the metabolic role of carbs and lipids

A

Carbohydrates and lipids are the primary sources of energy for metabolism

35
Q

Metabolic role of proteins

A

Enzymes control the rate of reactions in cells

36
Q

Metabolic role of vitamins

A

Vitamin C ~ helps form connective tissues like skin and gums

Vitamin D ~ the absorption of calcium for healthy bones and teeth

37
Q

Why is water important to organism ( 5 reasons )

A

•Water is a universal solvent
•Water provides a medium for reactions to take place in cells
•Water is slow to heat up and cool down
•Water is a good absorber of energy
•Water allows movement of materials in and out of cells

38
Q

What are the 2 main kinds of metabolic reactions

A

Anabolic and Catabolic

39
Q

What are anabolic reactions

A

Anabolic reactions use energy to make bigger molecules from smaller molecules using enzymes
Eg. Photosynthesis

40
Q

What are catabolic reactions

A

Catabolic reactions release energy when bigger molecules are broken down from smaller ones using enzymes
Eg. Respiration
