Photosynthesis |
|
Plants and other organisms convert light energy into chemical energy |
| |
|
Cell Respiration |
|
The set ofmetbolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into ATP |
| |
|
Equation Photosynthesis |
|
6CO2 + 6H2O + Energy -----> C6H12O6 + 6O2 |
| |
|
Equation Cell Respiration |
|
C6H12O6 +6O2 -------> 6CO2 + 6H2O + Energy |
| |
|
The bubbles formed during photosynthesis are made from what gas? |
|
Oxygen |
| |
|
Glycolysis |
|
Glucose is split into two molecules of a 3 carbon sugar
Produces 2 molecules of ATP, 2 molecules of pyruvic acid, and two high energy electron molecules carrying NADH are produced
Can occue with or without Oxygen
Without oxygen--- called fermentation |
| |
|
Citric Acid Cycle or Krebs Cycle |
|
Compounds NAD and FAD are reduced and carry high energy electrons to the next stage/ Occurs only when oxygen is present but doesn't use oxygen directly
|
| |
|
Electron Transport Chain |
|
Requires oxygen directly, electron transport chain is a series of electron carriers in the membrane of the mitochondria in eukaryotic cells/ High energy electrons are passed to oxygen/ in this process ATP is produced |
| |
|
Which stage of cell respiration produces pyruvate? |
|
Glycolysis |
| |
|
Which stage of cell respiration produces most ATP? |
|
Electron Transport Chain |
| |
|
Organelle involved cell respiration |

| |
|
Organelle involved in photosynthesis |
|
chloroplast |
| |
|
Aerobic Respiration |
|
Contains oxygen (more efficient) |
| |
|
Equation Fermentation |
|
C6H12O6--------> 2 C2H5OH + 2CO2
1 glucose molecule converted into two ethanol molecules and 2 carbon dioxide molecules |
| |
|
Endotherm |
|
ORganism that produces heat through internal means/ muscle shivering or increasing metabolism |
| |
|
Ectotherm |
|
Organisms which rely on environment for heat sources |
| |
|
Homeotherm |
|
Maintaining a stable internal body temperature regardless of external environment/ temp often hi |
| |
|
Poikilotherm |
|
Organism whose temperature varies considerable |
| |
|
Metabolism |
|
The sum of the physical and chemical processes in an organism by which its material substance is produce, maintained, and destroyed, and by which energy is made available
|
| |
|
Highest metabolism |
|
small organisms, endothermic organisms (produce own heat), warm
|
| |
|
How does CO2 effect rate of photosynthesis |
|
increases rate, speed up |
| |
|
Eng products of light reaction? |
|
ATP + NADPH |
| |
|
End product of dark reaction |
|
Sugar C6H12O6 |
| |
|
is photosynthesis endergonic or exergonic? |
|
endergonic |
| |
|
Cell respiration endergonic or exergonic? |
|
exergonic |
| |
|
Energy made during cell respiration? |
|
ATP |
| |
|
Two reactants used to make ATP? |
|
Glucose and oxygen (?) |
| |
Where does following rxn occur?
H20---> 2H + 02 |
|
Photosynthesis II, Thyllakoid |
| |
CO2-----> C6H12O6
Where occurs? |
|
Stroma of the chloroplasts |
| |
Glucose---> Pyruvate
Where occurs? What phase? |
|
Cell respiration: Glycolysis in cytoplasm |
| |
C6H12O6------> CO2
Where occurs? What phase? |
|
Cell respiration: Krebs Cycle:
Matrix of mitochondria |
| |
|
Where does fermentation reaction occur? |
|
Cytoplasm |
| |
Where does this occur?
making ATP using NADH |
|
mitichondria
Electron transport chain |
| |
|
Where does gas exchange occur in plants? |
|
Stomata |
| |
|
Making NADPH and ATP |
|
maybe cristae
electron transport chain |
| |
H20---> 2H + O2
What phase? |
|
Photosynthesis light reaction |
| |
What phase?
CO2---> C6H12O6 |
|
dark reaction photosynthesis (calvin cycle) |
| |
Making ATP using NADH
what phase? |
|
Cell Respiration: Electron Transport chain |
| |
|
Reduction |
|
Adding negative electrons to molecule/ adding hydrogen atoms
Making ATP using NADH-- NADH gives electrons to form ATP, therefore reduction |
| |
|
Oxidation |
|
Loss of electrons/ loss of hydrogen atoms
If one molecule is oxidized, must also reduce another molecule
Ie: NADH is oxidized when forming ATP because loses Hydrogen atoms/ electrons |
| |
|
In photosynthesis, electrons used in the electron transport chain come from what molecule? |
|
NADH |
| |
|
In cell respiration, electrons used in ETC come from what molecule? |
|
NADH and FADH2 |
| |
|
