1- describe three means by which enzymes can facilitate chemical reaction and state how the energy barrier of the reaction might be affected.

2- contrast the way in which metal ions, coenzymes, and prosthetic groups facilitate enzymes reactions.

3- explain why allosteric regulators often act on non-catalytic subunits and how those actions influence catalysis.

4- describe the feedback inhibition in the metabolic pathways and how could this provide an adaptive advantage to the organism.

There are many early evolutionary steps of photosynthetic organisms from the appearance of photosynthesis to various types of photosynthetic apparatus in the eukaryotic algae. Explain ten steps and how each advances a certain set of organisms.

1. What does the position of the testis tell you about spermatogenesis? Can you follow the path that sperm take as they exit the testis? Trace the vas deferens as it passes by the male accessory glands. What does the placement of these glands tell you about their contribution to the seminal fluid?

2.  Is the morphology of the spermatozoa the same as that of the human? Why do you think that sperm head morphology may differ among organisms? What is the chromosome number of the different stages of spermatogenesis (eg., haploid or diploid?). Can you see an organization in the seminiferous epithelium – how does this relate to the stages of meiosis?

3. Does the structure of the seminal vesicles appear amenable for sperm storage? Why or why not?

What are the predominant determinants of the EPP onset and duration following a presynaptic action potential?
