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
