Enzymes Are Catalysts Produced by Living Things Flashcards
What do living things have going on inside them all the time?
Thousands of different chemical reactions
Why do reactions need to get carefully controlled?
To get the right amounts of substances in the cells
How can you usually make a reaction happen more quickly?
By raising the temperature
Why is there a limit to how far you can raise the temp inside a living creature?
It’s cells will start to get damaged
What do enzymes act as?
Biological catalysts
What is a catalyst?
A substance which increases the speed of a reaction without being changed or used up
What do enzymes reduce the need for?
High temperatures
What do we only have enzymes for? What is this called?
To speed up the useful chemical reactions in the body. This is called metabolic reactions
