Problem:
Question 1: Explain the role of horizontal cells in generating the ON-bipolar cell receptive field. Specifically, compare the response of the ON bipolar cell when light is shone on the center of the RF (with dark surround) vs the situation when light is shone only on the surround (dark center).
Question 2: Glycolysis inhibiton by ethanol has been observed in isolated hepatocytes. Which glycolytic enzyme is affected? Explain your reasoning. Why does the addition of pyruvate partially overcome this inhibition?
