A) Glycolysis makes ATP exclusively through substrate- level phosphorylation. B) The enzymes of glycolysis are located in the cytosol of the cell. C) The end products of glycolysis are CO 2 and H 2 O. D) Glycolysis has steps involving oxidation-reduction reactions. E) Glycolysis can operate in the complete absence of O 2 . 33) Cellular respiration harvests the most chemical energy from which of the following? A) oxidative phosphorylation B) generating carbon dioxide and oxygen in the electron transport chain C) substrate-level phosphorylation D) transferring electrons from organic molecules to pyruvate E) converting oxygen to ATP 34) In glycolysis, for each molecule of glucose oxidized to pyruvate A) 6 molecules of ATP are used and 6 molecules of ATP are produced. B) 2 molecules of ATP are used and 2 molecules of ATP are produced. C) 4 molecules of ATP are used and 2 molecules of ATP are produced. D) 2 molecules of ATP are used and 6 molecules of ATP are produced. E) 2 molecules of ATP are used and 4 molecules of ATP are produced. 35) An enzyme catalyzes a reaction by A) lowering the energy of activation of a reaction. B) supplying the energy to speed up a reaction. C) lowering the Δ G of a reaction. D) increasing the amount of free energy of a reaction. E) changing the equilibrium of a spontaneous reaction. 36) Where is ATP synthase located in the mitochondrion? A) inner membrane B) electron transport chain C) cytosol D) outer membrane E) mitochondrial matrix 37) Glycolysis is thought to be one of the most ancient of metabolic processes. Which statement supports this idea? A) The enzymes of glycolysis are found in the cytosol rather than in a membrane-enclosed organelle. B) Glycolysis neither uses nor needs . C) Glycolysis is the most widespread metabolic pathway. D) Glycolysis is found in all eukaryotic cells. E) Ancient prokaryotic cells, the most primitive of cells, made extensive use of glycolysis long before oxygen was present in Earth's atmosphere. 38) Sucrose is a disaccharide, composed of the monosaccharides glucose and fructose. The hydrolysis of sucrose by the enzyme sucrase results in A) production of water from the sugar as bonds are broken between the glucose monomers. B) utilization of water as a covalent bond is formed between glucose and fructose to form sucrase. C) bringing glucose and fructose together to form sucrose. D) breaking the bond between glucose and fructose and forming new bonds from the atoms of water. E) the release of water from sucrose as the bond between glucose and fructose is broken. 40) What is one of the ways that the membranes of winter wheat are able to remain fluid when it is extremely cold? A) by increasing the percentage of unsaturated phospholipids in the membrane B) by decreasing the number of hydrophobic proteins in the membrane C) by increasing the percentage of cholesterol molecules in the membrane D) A and B only E) A, B, and C

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
