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...

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 called an electron transfer chain. 3. as the electron moves down, energy is lost from the electron and is released as ATP. 4. the loss...

The cytochrome b6f complex of the photosynthetic electron transport system is responsible for translocating 8 H+ into the thylakoid space from the stroma. However, a total of 12 H+ accumulate inside the thylakoid space as a result of photon absorption by PSII and PSI. What is the origin of the other 4 H+? correct answers The oxidation of 2 H2O to form O2 + 4 H+ + 4 e- Raffinose-series oligosaccharides are hard for humans to digest because correct answers humans do not have the enzyme necessar...

Describe and explain the steps in the light dependent reaction of photosynthesis 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 loss of elect...

BIOL 1301 Chapter 8 Review Verified Answers Why is photosynthesis important? Captures solar energy & converts it into chemical energy which is stored in sugar & other organic molecules What is the difference between an autotroph vs heterotroph? Give examples. autotroph- ultimate source of all organic compounts "self feeders" (producers) Ex. Oak tree, plants, algae heterotroph- obtain nutrients by ingesting other organisms "other feeders" (consumers) Ex. moose, bear, fungi, bacter...

T/F: as electrons are ejected from PSI they can enter a cyclic or non-cyclic pathway correct answer: true in which way is photosynthesis in plants different from that found in photosynthetic bacteria correct answer: plants have two reaction centers that generate oxygen (PSII) and NADPH (PSI) how does photophosphorylation differ from mitochondrial oxidative phosphorylation correct answer: ATP synthase translocates protons out of the thylakoid space - mitochondria conduct the protons from...
