1) Explain how photoreceptors are unusual in that they are depolarized in darkness (-30mV) and hyperpolarized by light? Explain by listing the key steps in phototransduction in a rod from photon to hyperpolarization.
2) What are the advantages of having 2 different types of photoreceptors (rods and cones)? Also, explain the difference between rods and cones.

Questions 1 pts Humans and many other diurnal animals have three types of cones - one stimulated maximally by blue light, a second maximally stimulated by green light, and a third stimulated maximally by red light. How can human beings see colors such as orange, yellow and purple? When red cones are stimulated, they inhibit blue and green cones. When blue cones are stimulated, they inhibit only green cones. Green cones when stimulated, do not inhibit other cones, but do...

DATA 4.1 Does Light at Night Affect Weight Gain? Numerous studies have shown that exposure to light at night is harmful to human health. A recent study? examines the effect of light at night on body mass gain in mice. Eighteen mice were randomly assigned to one of two groups: the Dark group had a normal light/dark cycle with darkness at night and the Light group had a dim light on at night, equivalent to having a television set on...

In Data 4.1 on page 258, we examine a study in which mice were randomly assigned to either a normal light/dark cycle or to have a light on around the clock. According to the paper describing that study, "The global increase in the prevalence of obesity and metabolic disorders coincides with the increase of exposure to light at night." The study is examining whether light at night plays a causal role in the obesity epidemic. In Data 4.1, we examine...
