BIOL 101 Quiz Energy and Information Liberty University Lynchburg Question 1 3.2 / 3.2 pts Which of the following phrases best describes the role of NADPH in photosynthesis? It absorbs light energy. It allows protons across membranes. It carries electrons from one stage of photosynthesis to the other. It converts useless wavelengths of light into more useful ones for photosynthesis. It prevents electron flow when no further energy is needed. Question 2 3.2 / 3.2 pts Each wavelength of light has its own temperature. separate source where it’s generated. energy level. molecular structure. interference pattern. Question 3 3.2 / 3.2 pts Reactants like hydrogen and oxygen molecules and are converted into a product like water molecules in the course of a normal sunny day at 25 degrees Celsius. a chemical reaction. the flow of water in a stream. hydrolysis processes. human exhalation. Question 4 3.2 / 3.2 pts ________ organisms build their own energy-rich molecules using solar energy. MicroAutotrophic Tropical Multicellular Marine Question 5 3.2 / 3.2 pts Enzymes lower activation energies by stressing exactly the bond in the reactant molecule that needs breaking. increasing the energy of the reactant molecules. increasing the kinds of reactant molecules involved in the reaction. converting reactants directly to products so that a chemical reaction is not needed. reversing the reactant’s chemical structure. Question 6 3.2 / 3.2 pts Which of the following substances would most likely enable a flagellum to drive a bacterium forward through the medium in which it is swimming? carbon dioxide DNA an amino acid phospholipid ATP Question 7 3.2 / 3.2 pts A lit match cannot continue to burn when the wood of the match stick is consumed. This statement illustrates the more general principle that energy must be supplied to the match to begin the burning process. energy forms are freely convertible, but energy can’t be created or destroyed. all chemical reactions in nature give off energy. lighters are more efficient than matches. if you need more money, just print it. Question 8 3.2 / 3.2 pts ________ and ________ are products of aerobic respiration. Glucose, water Glucose, ATP Carbon dioxide, water ATP, oxygen Oxygen, ADP Question 9 3.2 / 3.2 pts New molecules of glucose are produced within the nucleus of the cell. inside the cristae of the mitochondria. within the rough endoplasmic reticulum of the cell. within the stroma of the chloroplast. in the Golgi complex of the cell. Question 10 3.2 / 3.2 pts During the electron transfer reactions, protons (H+ ions) are pumped (moved) to one side of the inner membrane of the mitochondrion. The value of this pumping is that the proton gradient is then used . . . . . . . . .
