Proteins

Question 1

What are some of the functions of proteins?

Answer 1

• Structural
  
  • Skeletal Muscle
  • Cardiac Muscle
  • Cell Membrane
• Enzymes
• Hormones
• Antibodies
• Receptors

Question 2

What do enzymes function as?

Answer 2

Enzymes function as biological catalysts that speed up chemical reactions. They remain unchanged in the process and are not used up in a reaction. They lower the energy required for a reaction to take place. They are specific to certain substrates.

Question 3

What does SEP stand for?

Answer 3

Substrate —>Enzyme—> Product

Question 4

What does SAM stand for?

Answer 4

Starch—>Amylase—>Maltose

Degradation Reaction
Molecules are broken down

Question 5

What is a degradation reaction?

Answer 5

Reduces the size of the molecules

Question 6

What does HPCOW stand for?

Answer 6

Hydrogen Peroxide (H2O2) —>Catalase—> Oxygen + Water (O2+H2O)

Question 7

What are the optimum conditions for Enzymes?

Answer 7

• Certain PH (acid or alkali)

- Certain Temperatures (usually body temp)

Question 8

What happens to enzymes at high temperature?

Answer 8

At high temperatures enzymes will change shape - denatured - so will not fit the shape of the substrate
