State 3 properties of ATP that make it useful for distributing energy within cells.
What are..
- has a net release of energy when phosphate is removed
- process is reversible so cell can reuse ADP/ATP
- ATP can be produced through several different mechanisms
- relatively stable in the cytoplasm so it doesn't release energy prematurely
- small and soluble molecule that diffuses throughout cytoplasm quickly
- cannot diffuse through membrane so remains trapped in cell once produced.
300
The process of H+ ions (protons) diffusing down their electrochemical gradient, driving the synthesis of ATP.

The Calvin cycle continues throughout the life of a plant. In this cycle, triose phosphate is produced, which is used to form glucose.
In total, how many RuBP molecules must be regenerated in the process of creating one glucose molecule?
What is 6 RuBP?
3 RuBP per triose phosphate. Two Triose-phosphate to make a glucose.
400
The first decarboxylation reaction in aerobic cellular respiration
What is the LINK REACTION or pyruvate decarboxylation?
The link reaction is named thus because it links the products of glycolysis with the aerobic processes of the mitochondria
- Pyruvate is transported from the cytosol into the mitochondrial matrix by carrier proteins on the mitochondrial membrane
- The pyruvate loses a carbon atom (decarboxylation), which forms a carbon dioxide molecule
- The 2C compound then forms an acetyl group when it loses hydrogen atoms via oxidation (NAD+ is reduced to NADH + H+)
- The acetyl compound then combines with coenzyme A to form acetyl coenzyme A (acetyl CoA)

The light-independent phase of photosynthesis relies on molecules produced during the light-dependent phase.
Name the molecules produced during the light dependent phase that are used during the light-independent phase.
For each molecule named, describe how that molecule is used in the light-independent phase.
(Hint: be careful to name all times the molecule is used to be awarded points for this answer)
What are...
Specific molecules.....ATP and NADPH
When and how used...
NADPH provides the e– and H needed to reduce glycerate-3-phosphate into triose phosphate during the reduction phase of the Calvin cycle.
ATP provides the energy needed to reduce glycerate-3-phosphate into triose phosphate during the reduction phase of the Calvin cycle.
AND
ATP provide the energy needed to regenerate ribulose bisphophate (RuBP) into triose phosphate during the regeneration phase of the Calvin cycle.

What are...
A) NAD+ is being reduced into NADH
B) Isocitrate is being oxidized
C) Oxalosuccinate is being decarboxylated
D) These reactions occur in the mitochondrial matrix during the krebs cycle
500
Term that described the phenomena when the excited electron in a pigment molecule drops back down to its original level and the energy emitted is absorbed by an electron in the adjacent pigment molecule, causing it to become excited.
This process is called excitation energy transfer and it is repeated across the light-harvesting complex.
500
Two factors that lead to the loss of energy between trophic level in a food chain as shown in this pyramid of energy.
What are...
1. incomplete consumption
-ex: predators do not eat the bones/ hair of their prey yet the prey used energy to make the these structures. While this energy may be utilized by saprotrophs, it is lost by the primary food chain.
2. incomplete digestion
-ex:some animals do not digest tough fibrous plant matter containing cellulose. Indigestible material is egested in feces. While this energy may be utilized by saprotrophs, it is lost by the primary food chain.
3. cellular respiration
- organisms use their carbon compounds to fuel their life through cellular respiration. Only compounds not yet oxidized can be passed on to the next trophic level in a food chain.

The generation of a proton gradient by an electron transport chain followed by the subsequent generation of ATP by chemiosmosis is a universal process found in all living organisms.
What differs from organism to organism is the source of the energy and electrons used to generate the proton gradient. In this course you should have learned three different systems (two this year, one last year) that generate this proton force.
Briefly describe all three.
What are the...
1. Photophosphorylation in the light dependent phase of photosynthesis
- source of energy: solar energy (light)
-oxidation reaction providing electrons:
2 H2O --> O2 + 4H+ + 4e–
2. Oxidative phosphorylation in mitochondria
- source of energy: chemical potential energy
--oxidation reaction providing electrons: NADH (reduced NAD) --> NAD+ + 2e–
3. Oxidative phosphorylation in iron-oxidizing bacteria
- source of energy: chemical potential energy
-oxidation reaction providing electrons:
2 Fe2+ --> 2 Fe3+ + 2e–
