9 Which of the following best describes the result of using a catalyst in a chemical reaction.

. What best describes the relationship between the two sets of reactions of photosynthesis which are the light-dependent reactions and the light-independent reactions. A property that changes chemical composition of a substance is known as chemical property. During photosynthesis carbon dioxide and water are converted through a series of reactions into two products.

The rate of the forward reaction is equal to the rate of the reverse reaction. O The reaction is completed in a shorter amount of time. Are biological catalyst proteins.

The difference in free energy between the reactants and products of the reaction D. The melting of ice. The formation of a covalent bond between two amino acids.

From the statement itself the word react is present this signifies a reaction. Reactants and products are both present and their concentrations no longer change. B an exergonic reaction in which the entropy change in the cell is precisely balanced by an opposite entropy change in the cells surroundings.

Which of the following best describes a balanced reaction. High-energy sugars and oxygen gas. Dboth A and B.

What best describes what happens in a chemical reaction. Which of the following best describes an endothermic chemical reaction. A new substance with different properties is formed.

The temperature of the surroundings decreases. O The yield of product is increased. The difference in free energy between.

Substance that enhances the rate of a chemical reaction but itself is not permanently altered by the reaction. Which of the following is a chemical reaction. A reaction that has the same number and type of atoms on each side of the equation.

The process can only run in reverse. Changing a carbon atom to a nitrogen atom by radioactive decay. Amino acid side chains may.

The difference in free energy between the products and the transition state. For example precipitation reactivity toxicity etc are chemical property. The reaction can be reversed to get back the original substance.

Which of the following is the best description of the results of a chemical reaction. Which of the following best describes a chemical reaction in a state of equilibrium. Heat is released by the reaction and transferred to the surroundings.

Which of the following statements best describes the role played by molecules described in the reaction. O The yield of product is increased. BIf PO describes the reactionthen the outcome is given by AC.

Succinate is the substrate and fumarate is the product in the reaction. Answer choices The substance seems to disappear after dissolving in water. A graphical representation is the chemical equation.

AIf TE describes the reactionthen the outcome is given by AC. The potential energy of the reactants is higher than the energy of the products. Which of the following units can used to describe the rate of a chemical reaction.

A chemical property or reaction will always lead to the formation of a new product. 5Describe a cycloaddition reaction. Enone of the above.

The concentrations of the products are equal to the concentrations of the reactants. The temperature at which the reaction proceeds most quickly. MolLmin For the reaction A B 2 C which of the following best describes how.

A an exergonic reaction in which the free energy at equilibrium is higher than the energy content of the reaction at any point away from equilibrium. Have complex structures that are responsible for sophisticated functions. Making a hydrogen bond between a water molecule and a sugar molecule.

Mass is converted into energy. CIf TO describes the reactionthen the outcome is given by AC. The substance changes from liquid to solid at a low temperature.

Reactions occur in mild conditions required for living organisms. The correct answer is. AThe reactant has lost a sigma bondthe product has a new sigma bondand the pi.

A small cleft or crevice in an otherwise large protein molecule. Penicillin is an antibiotic that kills bacteria by binding to the active site of an enzyme involved in synthesis of the bacterial cell wall. Which of the following best describes the activation energy of a chemical reaction.

Option C is the correct answer.
