terms and concepts
Terms in this set (9)
organisms that make there own food.
organisms that depend on other organisms for their energy.
ATP (adenosine triphosphate)
is the small unit of usable energy. a compound that serves as a temporary energy storage molecule in all cells.
ADP (adenosine diphosphate)
the molecule that is produced when ATP is split to yeild energy
What is the primary need of all cells?
All cells depend on a constant supply of energy essential for them to perform all their cellular processes.
What are the two major groups of organisms based on how they obtain their energy?
Autotrophs and heterotrophs are the two major groups of organisms. Autotrophs make their own food. Heterotrophs depend on other organisms for their energy.
List the 3 components of an ATP molecule. What is the function of an ATP molecule?
The three components of an ATP moleculer are a 5 carbon sugar - ribose, Adenine a base found in DNA and a chain of three phosphate groups attached to the ribose backbone. The function of ATP is to store energy in small usable units.
Describe how ATP stores energy.
The key to how ATP stores energy is found in the bonds between the three phophate groups. They are bonded by high-energy covalent bonds.
What is the difference between ADP and ATP? Which holds more energy?
ATP has one more phosphate group than ADP. ATP holds more energy. Energy releases when ATP is broken down.
