300
DAILY DOUBLE (2 QUESTIONS IN 1)
A special class of proteins serve as catalysts for chemical reactions. What are they and how do they accomplish this?
Enzymes...decreasing activation energy
300
What are the 3 parts of a nucleotide?
1 of 5 nitrogenous bases, a phosphate group, and a pentose sugar (either ribose or deoxyribose)
400
What will cause an enzyme to lose its bond structure and fall apart. What is this called?
The wrong pH or temperature...This is called Denaturation
400
Starch has more of this type of energy compared to glucose.
Chemical energy: the energy stored in the bonds that hold atoms (matter) together
400
This hydrophobic coating on plants blocks the passage of water to protect against both water loss and excess water absorption
