SB1e Enzymes And Nutrition

Question 1

Difference in the way bacteria and animals get substances for energy growth and development.

Answer 1

Animals get substances for energy growth and development by digesting food inside their bodies .

Whereas bacteria get substances for energy growth and development by releasing digestive enzymes into their environments and then absorbing digested food into their cells

Question 2

What do digestive enzymes do in humans

Answer 2

They break down the large molecules in our food to the smaller subunits they are made of . The digested molecules are then small enough to be absorbed by the small intestine .

Question 3

What are the small molecules that are broken down by enzymes used for

Answer 3

Once the small molecules are absorbed by the body they can be used to build the larger molecules that are needed in cells and tissues

Question 4

What is synthesis

Answer 4

The process of building larger molecules from smaller subunits

Question 5

What do complex carbohydrates and proteins have in common

Answer 5

They are both polymers . This is as they are made up of many similar small molecules or monomers joined in a chain .

Question 6

Why does our body need enzymes

Answer 6

The breakdown of large molecules and synthesis happens very slowly . They happen way to slowly to supply the body with all it needs to stay alive and be active . Enzymes are used as catalysts to speed up the reactions

Question 7

What are enzymes

Answer 7

Biological catalysts the speed the rate of reactions and are a special group of proteins.

Question 8

What are enzymes

Answer 8

Biological catalysts the speed the rate of reactions and are a special group of proteins.

Question 9

What are the substances that enzymes work on called

Answer 9

Substrates and the substances produced are called products
