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?
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?
Which stage of cell respiration produces most ATP?
Electron Transport Chain
Organelle involved cell respiration
Organelle involved in photosynthesis
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
ORganism that produces heat through internal means/ muscle shivering or increasing metabolism
Organisms which rely on environment for heat sources
Maintaining a stable internal body temperature regardless of external environment/ temp often hi
Organism whose temperature varies considerable
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?
End product of dark reaction
Sugar C6H12O6
is photosynthesis endergonic or exergonic?
Cell respiration endergonic or exergonic?
Energy made during cell respiration?
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?
Where does this occur? making ATP using NADH
mitichondria Electron transport chain
Where does gas exchange occur in plants?
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
Adding negative electrons to molecule/ adding hydrogen atoms Making ATP using NADH-- NADH gives electrons to form ATP, therefore reduction
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?
In cell respiration, electrons used in ETC come from what molecule?
The final electron receptor in phtotsynthesis is...
The final electron acceptor of cell respiration is...
What is used by plants to harvest light?
What color of light is not absorbed, but reflected by plants?
True or false: A pH value higher than the optimum will icrease rate of photosyntheis?
False; needs to be close to optimum for best rate
Which type of plant closes its stomata in the day and stores CO2 in the night in the form of malic acid?
CAM (orchids, cacti, succulents)
What type of plant is corn?
