Exam Three: Basic Photosynthetic Reactions and Cellular Respiration

Photosynthetic organisms transform _____ sun energy into ______ chemical bond energy

kinetic; potential

Carbon dioxide and water have _____ potential energy

low

In photosynthesis reactions, energy has lots of _______ energy from _______

kinetic; sunlight

As a photosynthesis reaction occurs, potential energy

increases

Carbohydrates have lots of ______ energy stored in _______ _______

potential; chemical bonds

Basic photosynthesis reaction

3CO2 + 3H2O + Energy -> CH2OH + 3O2

all organisms use _______ ______ to take ____ energy in _______ bonds and store it as _______energy in ______

cellular respiration; potential; carbohydrate; potential; ATP

Photosynthesis needs

CO2

Photosynthesis releases

O2

Cellular Respiration needs

O2

Cellular Respiration releases

CO2

Photosynthesis energy storing pathway is in

chloroplasts

Cellular Respiration energy storing pathway is in

mitochondria

Cellular Respiration occurs in every

eukaryote

True or False: photosynthesis is only possible in some organisms

True

Overall, photosynthesis reactions are

endergonic and anabolic

Overall, Cellular Respiration reactions are

catabolic and exergonic

Cellular respiration

how cells release chemical energy

By the end of respiration, energy is now stored in the bonds of

ATP

Energy in the bonds of ATP is used to power

endergonic reactions elsewhere in the cell

Basic cellular respiration reaction equation

(CH2O)n + O2 +ADP + Pi -> CO2 + H2O + Energy

disorganized, unconverted energy given off by the reaction

heat

energy given off by cellular respiration is

ATP and Heat

Cellular respiration is nearly

photosynthesis in reverse

Glucose

C6H12O6

In cellular respiration glucose is

oxidized

in cellular respiration oxygen is

reduced

In cellular respiration, oxygen is the _______ agent

oxidizing

In cellular respiration, glucose is the _______ agent

reducing

Reducing agent

molecule that donates an electron and causes something else to be reduced

oxidizing agent

molecule that accepts electrons and cause something else to be oxidized
