13 Questions
How do enzymes lower the activation energy of a reaction?
By stretching the substrate bonds
Which enzyme class is responsible for transferring functional groups between donor and acceptor molecules?
Transferases
What is the function of Isomerases in biochemical reactions?
Carry out various kinds of isomerization reactions
In terms of enzyme function, what is the role of Ligases?
Join chemical groups using energy from ATP
How does temperature affect enzyme function according to the text?
Optimizes enzyme function initially, then may denature the enzyme at high temperatures
What is the primary reason behind stretching the bonds of the substrate in enzyme reactions?
To decrease activation energy
Which class of enzymes is responsible for adding water across a bond to hydrolyze it?
Hydrolases
In enzyme classification, which class is specialized in transferring phosphate groups?
Transferases
What is the function of Ligases in biochemical reactions?
Join two chemical groups with the use of energy from ATP
Which factor plays a vital role in determining the optimal functioning of enzymes?
Temperature changes
What kind of reactions do Isomerases catalyze?
Isomerization reactions
Which enzyme class is involved in adding or removing hydrogen atoms from chemical groupings?
Oxidoreductases
What is the significance of ATP in enzyme reactions catalyzed by Ligases?
Supplies energy for joining chemical groups
This quiz covers the topic of enzymes in biology, explaining what they are, how they work, and why they are important. Enzymes are proteins that act as catalysts to speed up chemical reactions in the body without being consumed in the process.
