Enzymes Flashcards
What are enzymes
enzymes are special proteins made by the cell that greatly speed up the chemical breaking and making.
When you add heat energy to a chemical system, what happens to the speed of molecular reactions
it speeds up the molecular motion
What are two problems in heat driven chemical reactions that the cell needs to solve
the breaking of chemical bonds
What is energy of activation
the push all reactants need. With energy of activation molecules don’t get destroyed by the heat.
What do enzymes change about the required activation energy
lowers the activation energy of reactions
What is a mother terms for enzyme
catalyst
What creat3 the unique shape of enzymes
The sequence of amino acids in it’s structure
Why does it take so much time for two reactants to react by great alone
because they don’t have enzymes
What does gene mutation does to the shape of enzymes
it will change the activity of the enzyme
Why does our body need so many different enzymes
to break down chemical substrat3 in our body
Is the speed of the reaction changed by variation in temperature freezing to 120
Fastest reaction under heat
Slowest reaction under cold water
Medium reaction under room temperature
Is the speed of the reaction influenced by the amount of enzyme
More enzymes create a faster reaction
Is the speed of the reaction influenced by the amount of susbtarte
No the amount of substrate didnt matter
Is the speed of reaction influenced by pH
The base solution had the faster reaction the acid solution did not create a reaction
The acid kills the enzyme
Are there natural substances that can inhibit enzyme action
Natural substances such as phenythylorean can inhibit the interaction between an enzyme and the substrate.
