Where do the light reactions of photosynthesis happen?
Thylakoids (or thylakoid membrane)
What is the name of the organelle where photosynthesis happens?
Chloroplast
What is the name of the organelle where respiration happens?
Mitochondria
Define metabolism
ALL of the chemical reactions within an organism (not just getting energy from food!)
Why do earthworms require oxygen?
Because they (like all cells) do cellular respiration, and oxygen is the final electron acceptor
Into what compartment does the PHOTOSYNTHESIS ETC pump protons?
Into the thylakoids
Do autotrophs, heterotrophs, or both do the light reactions?
Only autotrophs do photosynthesis
What is the role of oxygen in respiration?
It is the final electron acceptor after the ETC.
How did we get the leaf disks to sink at the start of our leaf disk lab?
We used vacuum power (the syringes) to fill the air pockets between leaf cells with baking soda solution.
What is the very first part of every caption?
Into what compartment does the RESPIRATION ETC pump protons?
The intermembrane space
Is the calvin cycle anabolic or catabolic?
Anabolic (building glucose)
Is the citric acid cycle anabolic or catabolic?
Catabolic (breaking down glucose)
What parts of respiration does FERMENTATION use?
Only glycolysis
Is the name in this title correctly formatted?
The effect of light color on pH in Chlorella vulgaris
No - the whole name should be italicized
Where does glycolysis happen?
The cytoplasm/cytosol
How are chlorophyll's electrons replenished in the light reactions?
From the splitting of water
What is the role of NADH and FADH2 in respiration?
They are high-energy electron carriers that are charged during the citric acid cycle and donate electrons to the ETC
Why were floating leaf disks a proxy for measuring photosynthesis in our leaf disk lab?
Oxygen is a byproduct of photosynthesis; more oxygen produced = the leaf disks float more
Name one part of an abstract that a caption DOES NOT have.
Broad background at the start
Bigger picture at the end
Where does the citric acid cycle (aka the krebs cycle) happen?
The mitochondrial matrix (the space inside the inner membrane)
Name whether the following molecules are inputs or outputs of photosynthesis: glucose, O2, CO2
Inputs: CO2
Outputs: glucose, O2
Name whether the following molecules are inputs or outputs of respiration: glucose, O2, CO2
Inputs: glucose, O2
Outputs: CO2
In our algae bead lab, if the solution of the pH became MORE ACIDIC, what does that mean for photosynthesis or respiration?
More acidic = more CO2 in the solution = more respiration (less photosynthesis)
Will oxygen production go up or down for a plant kept in the dark?
Down; if the light reactions aren't happening, the byproducts (including oxygen) won't be made
