What reaction builds polymers by removing water?
Dehydration synthesis creates polymers like starch by removing water
400
At extremely high temperatures, enzyme activity stops. What happened to the enzymes ?
It was denatured and lost its functional shape.
500
What happens to active transport if ATP is unavailable?
Molecules stop moving through the protein channel
500
Starch is being broken down into Maltose. Which chemical reaction is happening in the diagram?
When enzymes are broken down with the use of water, Hydrolysis is occurring.
500
What happens to enzyme activity at low temperatures?
The enzyme starts to denature, LESS chemical reactions are able to occur.
