All of the following statements about enzymes are true EXCEPT a. they speed up chemical reactions without changing themselves b. enzymes are proteins c. they are highly specific d. they are biological catalysts e. they are used up in a chemical reaction
help lower the activation energy needed for a chemical reaction and also regulate the speed of reactions within a cell. Two primary contributors to the amount of their activity are and Select one: a. Enzymes, pH, temperature b. Substrates, temperature, pH c. Organelles, pH, mitochondria 10 d. Mitochondria, temperature, substrates
Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...
The activation energy in a catalyzed reaction is lower than the activation energy in the same reaction uncatalyzed. True False
The following statements about enzymes are true, except: a. they are proteins tbat speed up chemical reactions. b. they are often consumed or destroyed in the reaction. c. the active site is the location of the chemical reaction. d. their function can be affected by salt concentration or pH
Which statement below is true only for a homogeneous catalysts? a. A homogeneous catalyst increase the rate of reaction by providing an alternative pathway with a lower activation energy. b. A homogeneous catalyst is a solid substance to which liquid or gaseous reactants will adhere to the surface of the catalyst. c. A homogeneous catalyst is when the catalyst is in the same physical state as the reactant. d. A homogeneous catalyst will eventually be consumed in a chemical reaction.
QUESTION 5 Which of the following statements about a catalyst is true? Catalysts decrease the activation energy of a reaction. Catalysts decrease the rate of the forward reaction. Catalysts cause a system at equilibrium to shift towards the products. Catalysts cause a system at equilibrium to shift towards the reactants. Catalysts decrease the rate of the reverse reaction.
Which of the following statements about activation energy is correct? Reactions may have negative activation energies. It is the minimum energy required for colliding reacting particles to react. It is the maximum energy a reacting molecule may possess. In general, reactions with higher activation energies are faster. Question 35 2 pts Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true false status of the statements using the choices. (1) Oxidation and...
