CR: Stage 1
What is the name of stage 1 of cellular respiration?
Glycolysis
What is the name of stage 2 of cellular respiration?
Citric acid cycle OR Krebs Cycle
What is the name of stage 3 of cellular respiration?
Oxidative phosphorylation
What is the name of stage 1 of photosynthesis?
Light dependent reactions
What is the name of stage 2 of photosynthesis?
Calvin Cycle OR Light Independent Reactions
Why do we perceive plants as green?
Chlorophyll reflects green light
In stage 1 glucose is broken down into what? (name of molecule and number of molcules)
2 pyruvate
Where does stage 2 of cellular respiration take place?
Matrix
How many molecules of ATP are made in stage 3?
32-34 ATP
What is required to initiate stage 1 of photosynthesis
light and water
Where does stage 2 occur?
Stroma
What processes of cellular respiration are considered aerobic?
Citric acid cycle and oxidative phosphorylation
What electron carrier(s) are used in stage 1? Differentiate between empty and filled.
Empty: NAD+
Filled: NADH
What is the name of the molecule, made in the intermediate stage that enters the cycle?
Acetyl CoA
Who brings the e- to the electron transport chain?
NADH and FADH2
What does photophosphorylation mean?
Using light to add a phosphate to ADP to make ATP
What are the inputs of stage 2 and where do they come from?
NADPH (LDR), ATP (LDR) and CO2 (air)
How is energy used from a molecule of ATP?
Break phosphate bonds
Where does stage 1 of cellular respiration occur?
Cytoplasm
What electron carrier(s) are used in stage 2. Differentiate between empty and filled.
Empty: NAD+
Filled: NADH
AND
Empty: FAD
Filled:FADH2
What is the final electron acceptor in the ETC? What product does it make?
O2 accepts the electron to make a water
What is the name of the electron carrier used in photosynthesis? Differentiate between empty and filled.
Empty: NADP+
Filled: NADPH
What is the name of the intermediate molecules produced in stage 2? What do they become?
2 G3P become 1 glucose
What are cristae and why are they important?
Folds in the inner membrane of the mitochondria that increase surface area and allow for more space for ETC, more space for ETC = more ATP
What are all 3 products of stage 1?
2 ATP, 2 pyruvate, and NADH
What are the products of stage 2?
CO2, NADH, FADH2, 2 ATP
Stage 3 of cellular respiration is made of what 2 structures?
Electron transport chain and ATP synthase
What are the 3 protein structures that an e- will travel to in order?
photosystem II > ETC > Photosystem I
Describe what is meant by ATP/ADP or NADPH/NADP+ being recycled in photosynthesis
ATP is broken down in stage 2 and used as energy, the resulting ADP is used in stage 1 in photophosphorylation to make a new ATP to be broken down in stage 2
NADPH donates an electron to make G3P or glucose in stage 2. It becomes NADP+ which can pick up a new electron from PS I in stage 1. The new NADPH can be used again in stage 2 and the cycle will repeat itself.
Final Jeopardy
What are the 2 types of fermentation. Write down the reaction equation of each.
Lactic acid fermentation:
C6H12O6 --> 2 ATP + Lactic Acid
Alcohol Fermentation
C6H12O6 --> 2 ATP + ethanol (alcohol)
