Q1. The neurotransmitter acetylcholine is made in the cytosol and then transferred into synaptic vesicles, where its concentration is more than 100 fold higher than in the cytosol. Synaptic vesicles isolated from neurons can take up additional acetylcholine if it is added to solution in which they are suspended but only in the presence of ATP. Na+ ions are not required for acetylcholine uptake, but raising the pH of the solution in which the synaptic vesicles are suspended increases acetylcholine uptake. In addition, transport is inhibited consistent with all these observations. Propose a mechanism that is consistent with all these observations.
Q2. In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluid since they cannot be stacked closely together. Of what benefit would this be for herbaceous plants that live through the winter?

Cross between pure red tomato and yellow tomato made all red F1 progeny. From the F2 progeny of 400 plants, 90 were yellow. Hypothesize that a single pair of allele is involved such that Y- = Red and yy = Yellow. Test this hypothesis using Chi squ..
