Tyr122 is important in the mechanism of the E. coli ribonucleotide reductase. The function of this amino acid in the mechanism is to carry out a nucleophilic attack on the substrate. coordinate water in the active site. generate the Cys439 radical species. hydrogen-bond to the phosphates of the substrate. correct answers generate the Cys439 radical species. Which of the following is the reaction for nitric oxide synthase? citrulline + NO + 1.5 NADP+ L-arginine + 1.5 NADPH + H+ + 2O2 ...

The term greenhouse effect refers to the idea that correct answers The temperature of the earth is increasing because of heat trapped by gasses such as CO2 What is the overall reaction for the Calvin Cycle, or dark reactions? correct answers 3CO2 + 6NADPH + 9ATP + 6H2O --> Glyceraldehyde-3-Phosphate + 6 NADP+ + 9ADP + 9Pi What is the overall balanced reaction for the light reactions of photosynthesis? correct answers 2H2O + 8photons + 2NADP+ + 3ADP + 3Pi --> O2 + 2NADPH + 3ATP For...

The Biosphere 2 project, in Tucson, Arizona, was an experiment involving a large sealed terrarium with humans and photosynthetic plants living in balance. Why did the project have to be interrupted after only a few months? Levels of CO2 rose to dangerous levels. The humans ran out of food. The plants stopped producing oxygen. The rate of photosynthesis was too high correct answers Levels of CO2 rose to dangerous levels The __________ is driven directly by photo- ns from the sun in photo...

WVU Biology 102 Exam 2 Questions and Answers Already Passed What products from the light reactions move on to the Calvin cycle? ATP and NADPH If a thylakoid membrane was punctured so that its interior was no longer separated from the stroma, which of the following processes would be directly affected? the synthesis of ATP A photosystem is a collection of pigments arranged in the thylakoid membrane When electrons from PSII are passed on to the electron acceptor, they are replaced ...

BIOL 1001 LSU Exam 3 Chs 7, 8, 9 Crousillac Questions and Answers Already Passed **Light-Dependent Reaction:** - The light-dependent reaction occurs only during the daytime and takes place in the thylakoid membrane where chlorophyll is located. - Oxygen is released as a by-product of this process. **Requirements for the Light-Dependent Reaction:** - The light-dependent reaction requires water and sunlight. **Flow of Electrons in the Light-Dependent Reaction:** - The flow of ele...

AQA BIOLOGY A-LEVEL PAPER 2 2024 WITH COMPLETE SOLUTIONS 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 fro...

Describe the events of fertilisation that occur after the acrosome reaction. - Answer -Membrane of sperm and egg cell fuse together -cortical granules release contents into zona pellucida -Zona pellucida thickens -Haploid nuclei fuse Explain how phospholipids form a cell surface membrane - Answer -Hydrophilic parts associate with water -Hydrophobic parts repel water -a bilayer forms with hydrophobic parts pointing in towards the centre of the bilayer Describe the role of the ...
