Enzymes are key components in biological reactions. Which of the following statements about enzyme function in biological systems is FALSE?
Enzymes are key components in biological reactions. Which of the following statements about enzyme function in biological systems is FALSE?
Enzymes increase the rate of a reaction, but do not change the free energy of a reaction.
Enzymes frequently work in metabolic pathways, such that the activity of one enzyme can affect the activity of a second enzyme in the pathway by altering the concentration of a substrate or product of the second enzyme.
Enzymes will alter the equilibrium of a reaction such that the enzyme increases the exergonic reaction relative to the endergonic reaction.
Even if the enzyme forms a bond with a substrate during a reaction, the enzyme returns to its original form at the end of the reaction.
Grasses collect energy from sunlight. Rabbits collect energy by eating grasses. Coyotes collect energy by eating rabbits. Which of the following organisms has the least amount of energy available to them (as compared to the amount of solar energy that hits Earth from space)?
A. Coyotes, because some of the original amount of energy was lost as body heat in grasses and rabbits
B. Grasses, because the energy has yet to be condensed as it moves through the food chain
indicate whether the following reactions are endergonic, requiring energy input, or exergonic, releasing energy:
endergonic, exergonic

- Set-up: A cell is able to extract energy from the molecule glucose after it breaks it's C-C and C-H bonds and replaces them with C=O and O-H bonds in CO2 and H20 in order to power unfavorable reactions. Questions: In a few brief sentences describe why cells can gain energy from this process. A successful answer should include the following: 1. How the action of breaking bonds relates to energy 2. How forming bonds relates to energy 3. Why some of these bonds store more energy to othersarrow_forwardExplain this Metabolic engineering (systems biology) is a systems-orientated approach to the analysis and synthesis of entire biological systems with the aim of controlling cellular properties.arrow_forwardWhich of the types of energy is NOT one a part of energy transformation chain during respiration and photosynthesis? mechanical energy- kinetic energy of moving objects nuclear energy - energy released during radioactive decay chemical energy - energy released when the products of a reaction have a lower free energy than the reactants potential energy stored in a gradient of concentrationarrow_forward
- Statement A: The flow of matter across the earth’s subsystems involves the transformation of matter into energy. Statement B: The breakdown of glucose molecule into H2O and H2O in the process of cellular respiration corresponds to the formation of a chemical form of energy adenosine triphosphate Both statements A and B are correct Statement A is correct, statement B is incorrect. Statement A is incorrect, statement B is correct Neither statement A nor statement B is correct.arrow_forwardWhich of the following describe energy unavailable to do cellular work? Group of answer choices Gibbs Free Energy Entropy Enthalpy delta Garrow_forwardThe energy in organic molecules is released in a series of steps rather than a single step because: the amount of energy released would be too much to capture in one reaction. more total energy is released in multiple steps than would be released in a single step. less total energy is released in multiple steps than would be released in a single step. it is not possible to release it in a single step. only a single electron can be moved at a time in a cellular reaction.

- An energy carrier, unlike an energy molecule, is rather difficult to produce due to their odd structures. is very unstable and thus do not exist for long outside of the cell. runs out of energy too quickly to be useful. just moves high-energy electrons to another source.arrow_forwardWhich of the following is false concerning ATP?

Note, there may be MORE THAN ONE correct answer, please choose all that are correct. ATP supplies the energy for most cellular processes ATP can be broken down into ADP + Pi ATP breakdown can be coupled to a reaction that requires energy ATP breakdown is an endergonic (energy-requiring) reaction ATP is a very stable and low-energy moleculearrow_forwardChemical bond energy: Is the energy used by photosynthesis for the fixation of carbon Is generated as usable energy for the cell Is generated by processes in the chloroplast and mitochondria All of the abovearrow_forward
