Key Area 4- Proteins Flashcards
Name 5 proteins
S- Structual
H- Hormones or Haemoglobin
A- Antibodies
R- Receptors
E- Enzymes
What is the function of enzymes
Speeds up chemical reactions
What is the function of Antibodies
Produced by white cells and protect body from harmful microbes
What is the function of hormones
Chemical messengers
Structural
Provide shape and suppport
Receptors
Movement Of Molecules
Haemoglobin
Carry oxygen around the body
What happens at the active site?
In the same way that a key fits into a lock, so a substrate is thought to fit into an enzymes active site. The enzyme is the lock and the reactant is the key
Name 2 degradation reaction (SAM)
. Amylase
Starch—————————-> maltose
. Catalase
Hydrogen peroxide——————> Oxygen + water
Name the reaction with protein as the substrate
Pepsin
Protein—————> Amino Acid
What is the reaction with a product of fatty acids
Lipase
Fat—————> Fatty Acids + Glycerol
What is the ONLY synthesis reaction
Phosphorlase
Glucose-1-phosphate——————————> starch
What’s optimum temperature
Enzymes work faster at warm temperature. The temperature at which enzymes are most active.
synthesis
the product is being made from the enzymes and substrate
Degradation
The product is broke down from the substrate
