Glycolysis
How much atp is produced at this stage?
2
How much atp is produced at this stage?
2
34
Chloroplast (Photosynthesis) and Mitochondria (Cellular Respiration)
Because solar energy is required for the light-dependent reactions but not the light-independent reactions
Where does glycolysis occur?
In the cytoplasm
Where does the krebs cycle take place?
In the mitochondrial matrix
Where does this stage occur?
Inner mitochondrial membrane. (Mitochondrial membrane is also fine)
What are the reactants of photosynthesis? Cellular Respiration?
Photosynthesis: Carbon dioxide and water (sun is also ok)
Cellular respiration: Glucose and Oxygen
Light-dependent = thylakoid membranes
Light-independent = stroma
How many pyruvates are derived from one glucose molecule? State the amount of carbons too.
1 glucose --> 2 pyruvates.
Glucose has 6 carbon molecules and is split up into 2 3-carbon molecules aka pyruvates.
What gas is released in the Krebs cycle?
CO2
What atom accepts the hydrogen ion at the end of the ETC and what do they combine to make?
Oxygen. H20 or water
What is the one component of photosynthesis that is not recycled and must constantly be available?
Energy
What is chemosynthesis? What are examples of organisms that conduct it?
The process of an organism making its own food using chemicals (“chemo”) instead of sunlight (“photo”) like in photosynthesis.
Examples: Organisms at the bottom of the ocean or dark caves.
What hydrogen-carrying molecules are produced during glycolysis?
NADH.
How many molecules of CO2 are produced from one pyruvate? How does it do this?
3. This is done because the pyruvate has 3 carbons. It splits itself up, donating its Carbons to bond with oxygen.
What is the name of the enzyme structure at the end of the ETC and what does it produce?
ATP Synthase and it produces ATP
Compare the reactants and products of photosynthesis and cellular respiration. What are the similarities and what are the differences.
The reactants of photosynthesis are the products of cellular respiration and vice versa. They are opposite processes containing the same components.
What are the two energy carries that go from the light-dependent reaction to the light-independent?
ATP and NADPH
What does the glyco- and the -lysis mean in the term glycolysis?
Glyco means sugar and lysis means splitting apart. AKA the splitting apart of sugar (glucose)
What two-hydrogen molecules are formed during the Krebs Cycle? How does this happen?
Pyruvate splits its remaining hydrogens to bond to NAD making NADH and FADH2.
Is the electron transport chain aerobic or anaerobic? Explain
It is an aerobic process meaning it requires oxygen to function. The oxygen bonds with the electrons and Hydrogen ions to make water.
"Plants can survive on their own because they make their own food. Animals can't survive on their own but need plants for survival" Explain why you agree or disagree with this statement. (1 min)
This is true because plants only need co2, water, and sunlight which they get on their own. Animals are dependent on plants to obtain energy and cannot obtain energy on their own from photosynthesis. They must eat in order to conduct cellular respiration.
If the light-independent reactions don't obtain light in order to conduct itself, how does it power its reactions?
It uses the energy from the “energy-carrying molecules” from the light-dependent reaction
