Photosynthesis And Cellular Respiration Review Flashcards
Photosynthesis
The process where plants or producers make sugars like glucose using the suns light energy
Photosynthesis balanced equation
6CO2 + 6H2O yields with sunlight and chlorophyll C6H12O6 +6o2
Photosynthesis reactants
Carbon dioxide and water
Photosynthesis products
Glucose and oxygen
Photosynthesis light reaction
Water is split into hydrogen and oxygen molecules
Light reaction occurs in
Grana/thylakoids
Light reaction reactants
Water and sunlight
Light reaction products
Hydrogen and oxygen
Dark reaction
Hydrogen and carbon dioxide combine to form glucose
Dark reaction occurs in
Stroma
Dark reaction reactants
Hydrogen and carbon dioxide
Dark reaction products
Glucose
What organisms perform photosynthesis
Plants/autotrophs/producers/photosynthetic organisms
What would happen without sunlight
Producers would not be able to make sugar to use as food and would die off
Heterotrophs would not be able to get energy and would die off
Cellular respiration
The process where mitochondria breaks down sugars or glucose to make energy
Cellular respiration balanced equation
C6H12O6+6O2 yields 6CO2+6H2O+36 ATP
Cellular respiration reactants
Glucose and oxygen
Cellular respiration products
Carbon dioxide water and energy
Glycolysis
Glucose is broken down into 2 Pyruvic acid molecules(pyruvate)
Glycolysis occurs in
Cytoplasm
Glycolysis equation
Glucose yields pyruvic acid
Glycolysis electrons are carried via
NADH
Glycolysis produces
2ATP
Citric acid cycle or
Krebs cycle
Citric acid cycle occurs in
Matrix of mitochondria
Citric acid cycle electrons carried via
NADH AND FADH2
Citric acid cycle produce
2 ATP
Electron transport chain occurs in
Cristae(inner membrane of mitochondria)
What happens in the electron transport chain
Electrons from NADH and FADH2 pass through a series of enzymes to oxygen which becomes water and hydrogen protons pass through ATP synthase to create 32 ATP
Anaerobic respiration also called
Fermentation
Differences in fermentation in bacteria and mammals
Bacteria uses alcohol fermentation And mammals use lactic acid fermentation
Fermentation produces
2ATP
ATP stands for
Adenosine triphosphate
Where is energy stored in ATP
Chemical bonds
Why do organisms undergo fermentation
It is not always possible for them to get all the oxygen their cells need to go through the process of cellular respiration fermentation allows them to keep producing ATP
Cellular respiration works with photosynthesis
The products of cellular respiration are used as the reactants of photosynthesis they are exact opposites
Why do autotrophs perform cellular respiration
So that the energy stored in the chemical bonds of glucose can be changed into the more accessible form of energy in ATP
Which 2 biomolecules are used in cellular respiration and photosynthesis
Sugar(glucose) and protein( ATP)
Diffusion
Molecules move from high to low concentration
Osmosis
Water molecules move from high to low concentration
