Enzymes, Proteins and Catalysts

Enzyme reaction rates are affected by

1. Shape- "Lock and Key Model" if it is the wrong shape it will not work. 2. Temperature- each enzyme works best at a specific temperature 3. Ph-- each enzyme works best at a specific ph

Which condition is necessary for enzymes and hormones to function properly in the human body?

These chemicals must have a specific shape

All enzymes

affect the rate of chemical reactions

Because catalysts themselves are not changed or used up, they can carry out the same function

again and again

enzyme amalyse function

break down carbs; found in saliva

four functions of enzymes

digestion, synthesis, cellular respiration and photosynthesis

which characteristic allows enzymes to function in a specific way?

each enzyme has a characteristic shape

All enzymes

effect the rate of chemical reactions

Catalysts are also known as

enzymes

Which substances are necessary for the synthesis of most materials in an organism?

enzymes

which substances are necessary for the synthesis of most materials in an organism

enzymes

The function of a specific enzyme is most directly influenced by its

physical shape

catalyst

substance that can effect the rate of a chemical reaction without itself being changed or used up during a reaction
