Biology 1202B Lecture Notes - Lecture 10: Dialysis, Visual Phototransduction, Light-Independent Reactions
Document Summary
Cycle 5: lecture #10 exercise and application of concepts i. Both have a pigment bound to a protein. Light is used to make glucose and other essential molecules, Absorption of light leads to flow of electrons down the etc to harvest the energy to make nadph and atp for the calvin cycle and other metabolic pathways in the chloroplast to change in isomeric structure. Light is used to acquire information about the environment. Absorption of light leads to phototransduction cascade leading to an action potential that allows sensing direction of light (chlamy) or sends message to the brain (in humans) Energy from the photon is used to break bonds in retinal for isomerization which ultimately leads to an action potential. Function of the kidneys: remove waste products of metabolism from blood, homeostatic functions: regulation of electrolytes, acid-base balance, fluid balance, blood pressure. Over two million people with kidney failure worldwide receive on going hemodialysis treatments to sustain their life.
