It is likely that cyanobacteria played a key role in launching the carbon cycle because they were among the first organisms capable of photosynthesis. Photosynthesis involves a set of chemical reactions driven by sunlight (hy) and consumes carbon dioxide and water and turns these starting materials into glucose (C6H1206) and oxygen. A balanced symbolic chemical equation modeling photosynthesis is shown below. For every one mole of carbon dioxide consumed, how many moles of oxygen are produced? 6 CO2 (g) +...

D Question 19 2 pts Which of the following statements best describes the primary role played by oxygen in cellular respiration? It yields energy in the form of ATP as it is passed down the electron transport chain. It serves as an acceptor for carbon, forming CO2 in the citric acid cycle. It oxidizes glucose to form two molecules of pyruvate. It serves as the final acceptor for electrons from the electron transport chain. Question 20 2 pts Which of...

The sulfur cycle differs from the nitrogen cycle in that Choose one: A. only sulfate, and not nitrate, can be used as an electron acceptor at the end of an electron transport chain. B. only nitrogen, and not sulfur, exists in multiple oxidation states. C. only H2S, and not NH3, is a substrate for photolysis by phototrophs. D. prokaryotes play an important role in nitrogen cycling but not sulfur cycling,

Alanine is an allosteric inhibitor of liver pyruvate kinase. What might be the reason? In choosing your answer consider the role of alanine in the glucose-alanine cycle. Select one: a. It reduces the amount of ATP available for the urea cycle. b. It reduces the availability of pyruvate as an acceptor for the amino-groups derived from alanine. c. It reduces the use of phosphenolpyruvate in glycolysis. d. It increases the synthesis of glycerol-3-phosphate for fat biosynthesis. e. It reduces the...
