ATP Flashcards
1
Q
ATP
A
- Adenosine Triphosphate
- nucleotide
- performs many essential roles on the cell
- major energy currently of the cell, providing the energy for most of the energy consuming activities of the cell.
2
Q
Energy
A
When the third phosphate group of ATP is removed by hydrolysis, a substantial amount of fre energy is released.
3
Q
Synthesis of ATP
A
- occurs in the cytosol by glycolysis
- occurs in the mitochondria by cellular respiration
- occurs in chloroplasts by photosynthesis
4
Q
Consumption of ATP
A
- Atp powers most of the energy- consuming activities of cells such as, synthesis of fats, and polysaccharides
- nerve impulses
- muscle contraction
- bioluminescence
5
Q
Redox Reactions
A
Oxidation Reduction Reactions
6
Q
RR: Oxidized
A
An atom or molecule that loses an electron
7
Q
RR: Reduced
A
The one that gains an electron
8
Q
RR: Reducing agent
A
An atom or a molecule that is oxidized
9
Q
RR: Oxidizing agent
A
Atom or molecule that is reduced
10
Q
High energy Bond
A
Rep. by a red wavy line, bonds are actually weak bonds with low bond energies. They can break easily and release energy.
11
Q
Energy coupling
A
transfer of energy from one reaction to another in order to drive the other reaction
usually between exergonic and endogenic reactions
