Cellular Respiration + Photosynthesis Flashcards
Rubisco’s role:
To take CO2 and Hydrogen from NADPH and, using ATP, turn it into glucose
Where does the light dependent stage occur in C4 plants?
Mesophyll Cells
Where does the light independent stage occur in C4 plants?
Bundle Sheath Cells
Why do C4 plants separate dependent and independent stages?
So Rubisco is not exposed to oxygen, and hence cannot undergo photorespiration
Outline steps that could be carried out to identify unknown plant type
1) Ideal Temp
2) Pathway to fix CO2
3) When is stomata open?
4) How much photorespiration?
5) How much water loss?
6) Plant growth
7) Physical comparisons between known plants
Plus:
- Increase sample size to validate results
- Vary initial variables
How is ATP generated in the Electron Transport Chain?
- NADH and FADH2 are inputs of the electron transport chain, and their protons (and accompanying electrons) pass through the proteins in the ETC
- The Hydrogens move through ATP synthase (the final protein) to generate ATP
Inputs of Glycolysis
- 2ADP + 2Pi
- NAD+
- Glucose
Outputs of Glycolysis
- 2ATP
- NADH
- 2 Pyruvate
Inputs of Krebs Cycle
- 2 Pyruvate
- 2ADP + 2Pi
- NAD+
- FAD
Outputs of Krebs Cycle
- CO2
- FADH2
- NADH
- 2ATP
Inputs of ETC
- FADH2
- NADH
- 26/28 ADP + 26/28Pi
- Oxygen
Outputs of ETC
- 26/28 ATP
- Water
- FAD
- NAD+
When is the Calvin Cycle?
Light independent stage of photosynthesis
What is Carbon Fixation?
When carbon dioxide is converted into organic molecules, like glucose or malate
Where are chloroplasts most abundant?
- In shaded areas of the plant
- e.g. under leaves
