Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i. e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
