Proteins and enzymes Flashcards
What are examples of protein.
Antibodies, enzymes and hormones.
What do ANTIBODIES do?
Help to fight infections in the body and defend it from invadars.
What do ENZYMES do?
Digest your food and make the proteins in our body.
What do HORMONES do?
Send messages around your body.
What is an example of: STRUCTURAL PROTEIN?
Keratin in hair and nails.
What is an example of: GLOBULAR PROTEIN?
Enzymes and hormones.
What do SYNTHESIS ENZYMES do?
Join small moleclues together to make larger molecules.
What do DEGRADATION ENZYMES do?
Break down big moleclues into smaller molecules.
Antibodies, enzymes and hormones are all examples of…?
Protein.
What: Help to fight infections in the body and defend it from invadars?
Antibodies.
What: Digest your food and make the proteins in our body?
Enzymes.
What: Send messages around your body?
Hormones.
What enzymes: Join small moleclues together to make larger molecules?
Synthesis enzymes.
What emzymes: Break down big moleclues into smaller molecules?
Degradation enzymes.
What is: the substance an emzyme works on?
Substrate.
What is: the substance made during the reaction?
A product.
Explain how an enzyme works.
An enzyme has a groove on it called an active site. This is when the substrate joins on. Only the enzymes own substrate(s) has the right shape to fit the active site.
Enzymes are…?
Specific.
What substrate can AMYLASE break down? (only)
Starch
What substrate can PEPSIN break down? (only)
Protein
What substrate can LIPASE break down? (only)
Fat
How can an emzyme become denatured?
By high temperature and some chemicals.
What does denatured do to the enzyme?
It changes shape and is no longer specific.
What is a: SUBSTRATE?
The substance an emzyme works on
What is a: PRODUCT
The substance made during the reaction.
If the temperature of an emzyme further increased after being at the optimum temperature what will happen to activity?
Activity will start to decrease.
What happens to enzymes at low temperatures.
It is inactive.
Biological detergents (bio) contain enzymes made by…?
Bacteria
In bio detergents what do the enzymes do?
They digest the food stains at a low temperature.
What is a disadvantage of ‘bio’ detergents?
Some people can have allergic reactions to them and get rashed or ezcema. (these people use ‘non-bio’)
