Bio 172 Exam 2 Questions and Answers Already Graded A What is true about the reaction show below? C6H12O6+6O2 -> 6CO2+6H2O+energy O2 is reduced during the reaction Quinone is an electron carrier that shuttles electrons between Complex I and Complex III. What is true about electron transfer between Complex I and Complex III? Quinone gets oxidized by Complex III. Below is the equation that represents Phase 3, the energy producing or payoff phase of glycolysis. Using the equati...

AP BIOLOGY UNIT 2 TEST QUESTIONS WITH VERIFIED ANSWERS Compare and contrast P2 and P1. Photosystem II begins , which absorbs wavelengths at a wavelength of 680 nm. Here, energy is absorbed and passed along until it reaches P680 chlorophyll. When this chlorophyll is excited, it sends its electrons to the primary electron acceptor. Electrons are taken from H2O and passed to P680 to replace the electrons given to the primary acceptor. This forces O2 to form. The electrons are passed to ph...

AQA Biology A-Level Paper 2 Exam Questions & Answers (Graded A+) AQA Biology A-Level Paper 2 Exam Questions & Answers (Graded A+) describe and explain the steps in the light dependent reaction of photosynthesis - ANSWER - 1. photoionisation: light reaches chlorophyll in PSII, which is absorbed by an electron, which becomes excited and moves to a higher energy level. 2. the electron passes to a carrier protein in the thylakoid membrane, and is passed down a series of carrier molecules call...

Understand differences between catabolism / anabolism and what these reactions have to do with metabolism - anabolism: simple substances are synthesized, ENDERGONIC, needs input of energy, ex: peptidoglycan, enzymes, exotoxins catabolism: breakdown of complex molecules, EXERGONIC, energy released metabolism needs both, glucose is broken down via catabolism and the energy from that is used to make enzymes via anabolism so that the bacteria can 'eat', anabolic and catabolic reactions are c...

describe and explain the steps in the light dependent reaction of photosynthesis - correct answer 1. photoionisation: light reaches chlorophyll in PSII, which is absorbed by an electron, which becomes excited and moves to a higher energy level. 2. the electron passes to a carrier protein in the thylakoid membrane, and is passed down a series of carrier molecules called an electron transfer chain. 3. as the electron moves down, energy is lost from the electron and is released as ATP. 4. the lo...
