AQA biology a-level paper 2 AQA biology a-level paper 2 describe and explain the steps in the light dependent reaction of photosynthesis - ANS 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 lo...

Open-Book Quiz NAME: Tamela Street 1. How does the frequency of urination vary? (See page 543 in your textbook.)  The frequency of urination varies.  Infants void from 5 to 40 times a day. The preschool child may void every 2 hours. The adult voids from 5 to 10 times a day. On average, the adult male voids 300 to 500 mL each time, and the adult female voids 250 mL. There should be at least an hourly urine output of 30 mL. This reflects adequate kidney perfusion. 2. What factors af...
