24
Q

What is biology

A

Study of living organisms.

25
Q

Biology derives from greek

A

Bio: Life
Logos: Study

26

32
Q

Build or broken through metabolic reactions

A

Lipids, carbohydrates, protein

33
Q

Enzymes defnition

A

Biological molecules that help speed up the proces of metabolism by making the subside enter the active side and the chemical reaction happens

34
Q

Why enzyms importat

A

The rocess would be too slow and the living orgaism would die

35
Q

Anabolic reaction two ex

A

Combine two small molecules into a larger one.

  1. Photosynthesis: uses carbon dioxide to create oxygen
  2. Glycogene: stores glucose like when you eat alot of sugar
36
Q

catabolic reaction two ex

A

Breaks down a larger molecule into smaller ones

  1. eting lots of sugar particles break down to create chemical energy
  2. Diggestion when you eat something and dissolves in your body with water
37
Q

Balance diet

A

Carbohydrates for energy, proteins very important creates enzymes and lipids are long term energy we need to store
