A substance Y has a molar extinction coefficient of 4M-1cm-1. You took 1mL from the stock of solution Y, added it to 4mL of water. The new diluted solution Y has a measured value of 1% Transmittance (after being properly blanked). The path length (l) is 1cm. What is the concentration of the substance Y in the stock?
What is 2.5M?

The chromatography paper is this and the chromatography solvent is this (in terms of hydrophobicity)
What is the paper is hydrophilic and the solvent is hydrophobic (so hi Rf means?

Where does photosynthesis occur in bacteria?
What are the double plasma membranes?
300
An organism whose chloroplasts are embedded in the cytoplasm
What is elodea?
300
This is what the aperture diaphragm does, also do you fix AD first, or Field Diaphragm first?
What is controls the amount/intensity of light that goes through the slide and can increase or decrease contrast? and FD
300
The aldehyde of the maltose is the (reducing/oxidizing) unit
What is reducing unit?
300
This is why you use a sodium phosphate buffer that lacks sugar for the Hill runs
What is lysing of chloroplast membrane, while keeping thylakoid membranes intact
300
This is what DCMU does in thylakoids and why
What is blocks electron transport between PSII and PSI, which prevents ATP, and DCPIPH/NADPH production
400
In this organism, cytoplasmic streaming occurs in the cytosol between a large vacuole and the plasma membrane
What is Nitella?
400
A student makes the following preparation. She takes 400 grams of chemical A and add water to a final volume of 1 Liter. The molecular weight of chemical A is 200 grams/mole. This solution is referred to as solution 1. She then takes 2 ml of solution 1 and adds it to 8 mls of water and mixes it; this is solution 2. She then take 5 ml of solution 2 and adds it to 5 mls of a water and mixes it; this is solution 3. She then takes 1 ml of solution 3 and adds it to 9 mls of water and mixes it; this is solution 4. What is the concentration of A in solution 4? Note units.
What is 20mM/L
400
This is a property of amylase that allows the lab to function
What is amylase breaks large molecules of polysaccharides first?
400
This is what would happen if DCMU and methylamine were added to your enriched chloroplast solution under light conditions
What is nothing? (same as just DCMU)
400
This type of tissue is the common top lining of bodily surfaces and cavities
What are epithelial cells?
500
Why does cytoplasmic streaming slow down with the addition of FCCP in Nitella?
What is proton gradients are dissipated across the membranes of mitochondria and chloroplast, preventing ATP production?
500
These are two ways to increase resolution
What is increase NA or decrease wavelength?
500
DNS reacts with (alpha/beta) glucose, and therefore (can/cannot) react with cellulose
What is both and can?
500
This is what happens to ATP concentrations when methylamine is added to your enriched chloroplast solution. Also this is how methylamine does this
What is decreased? What is neutralizing the proton gradient across the thylakoid membrane and storm? (what about O2 concentrations? NADPH/DCPIPH concentrations?)
500
This is what the antennae pigment-protein does
What is increases surface area for photon absorption? (same thing as light harvesting complexes)
