Defence

Answer 11

• Function: Involved in the immune system by. recognizing and destroying pathogens.
• Examples: Antibodies (immunoglobulins),complement proteins

Question 12

The following proteins are critical to the function of the cell

Defintion and funtions of the protein
Motor/contractile

Answer 12

• Function:Involved in the contraction and movement of muscles, the movement of internal cell contents around the cytoplasm and the movement of cellia and flagella
• Examples: Mypsin and actin- work together to enable muscle contraction

Storage

Answer 13

• Function: Act as reserves for metal ions and other molecules throughout the organism.
• Examples: ferritin- Storage of irons
  Casein- Storage of amino acids,carbohydrates, and minerals

Question 14

Summarize the four levels of protein structure?

Answer 14

• Primary: The sequence of amino acids.
• Secondary: Their arrangement into alpha-helices, beta-pleated sheets, or random colis
• Tertiary: The functional 3d shape of the protein
• Quaternry: The bonding of multiple chains together
