What else can I help you with?
A chemical reaction in a living cell occurs in the presence of a specific protein molecule?
The specific protein molecule in a cell acts as a catalyst, facilitating the chemical reaction to occur more efficiently or at a faster rate. The protein molecule binds with the reactants, stabilizes the transition state, and lowers the activation energy required for the reaction to proceed. Without the presence of this protein molecule, the reaction may occur, but at a significantly slower rate.
Which represents the collection of chemical reaction that occur in the cell?
its metabolism
What does an enzyme do to activation energy?
Enzymes reduce the activation energy required for a chemical reaction to occur by stabilizing the transition state of the reaction. This allows the reaction to proceed more rapidly than if it were to occur without the enzyme present.
What energy is required for the reaction to occur?
Activation energy. The kinetic energy from collisions between particles is used to reach the transition state
The cell potential of an electrochemical cell is positive. What does that tell you about the redox reaction?
A positive cell potential indicates that the redox reaction is spontaneous under standard conditions. This means that the reactants have a higher free energy than the products, leading to a favorable reaction that can occur without external energy input. Additionally, it suggests that the reduction half-reaction has a greater tendency to gain electrons compared to the oxidation half-reaction losing them.

What does cytoplasm does in a animal cell?
it is the place for the biochemical reaction to occur.
What does it mean if a cell has positive voltage?
The reaction will occur naturally
Which represents the collection of chemical reaction that occur in the cell?
its metabolism
What does a positive cell voltage mean?
The reaction is spontaneous.
What does an enzyme do to activation energy?
Enzymes reduce the activation energy required for a chemical reaction to occur by stabilizing the transition state of the reaction. This allows the reaction to proceed more rapidly than if it were to occur without the enzyme present.
What is the energy barrier?
The energy barrier is the minimum amount of energy required for a chemical reaction to occur. It represents the energy difference between the reactants and the transition state of the reaction. Overcoming this barrier allows the reaction to proceed.
What energy is required for the reaction to occur?
Activation energy. The kinetic energy from collisions between particles is used to reach the transition state
What term refers to the difference between the energy of the transition state and the energy of the reactants?
The term that refers to the difference between the energy of the transition state and the energy of the reactants is activation energy. It represents the energy threshold that must be overcome for a chemical reaction to occur.
What presence of an speeds up a reaction?
The presence of a catalyst can speed up a reaction by providing an alternate pathway with lower activation energy, allowing the reaction to occur more quickly. Catalysts work by facilitating the formation of transition states and by stabilizing reaction intermediates.
How do enzymes alter the equilibrium of a chemical reaction?
Enzymes alter the equilibrium of a chemical reaction by lowering the activation energy required for the reaction to occur, thus speeding up the rate at which the reaction reaches equilibrium. This is achieved by stabilizing the transition state of the reaction, making it easier for the reactants to form products.
How does the enzyme catalyze the reaction?
Enzymes lower the activation energy required for a reaction to occur by stabilizing the transition state of the reaction, making it easier for the reaction to proceed. This lowering of activation energy allows the reaction to happen more quickly and efficiently. Enzymes achieve this by binding to the substrates and facilitating the formation of the transition state.
