What is a sequence of chemical reactions within a cell?
The reactions that occur in cells are both anabolic (building up) and catabolic (breaking down). The catabolic reactions provide the energy for the anabolic reactions. The sum total of all catabolic and anabolic reactions in the cell is called metabolism.
Which of the following is not required in a chemical reaction?
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
What are the substances that are added to a reaction speed up the reaction?
Substances that are added to a reaction to speed it up are called catalysts. Catalysts work by providing an alternative pathway with lower activation energy for the reaction to occur, thus increasing the rate of the reaction without being consumed themselves.
What is a chemical reaction in which the products reform the original reactant?
Enzyme catalyzed reactions are the chemical reactions that occur in series where the product of one reaction serves as the reactant in the next reaction. These reaction pathways allow a cell to grow and reproduce.
What represents the collection of chemical reaction that occur in a cell?
METABOLISM
What are the intermediate products of the Krebs Cycle?
Intermediates are compounds formed within a metabolic pathway(which is a group of biochemical reactions that occur in a sequence- Anabolic or catabolic)
What is the reverse of a spontaneous reaction, and how does it differ from a nonspontaneous reaction?
The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.
What does a double arrow mean in a chemical reaction?
A double arrow in a chemical reaction indicates that the reaction is reversible, meaning it can proceed in both the forward and reverse directions. The reaction can reach an equilibrium where the forward and reverse reactions occur at the same rate.

What is this substance aids in the chemical reaction process?
A catalyst is a substance that aids in the chemical reaction process by increasing the rate of the reaction without being consumed itself. Catalysts work by providing an alternative pathway with lower activation energy for the reaction to occur.

METABOLISM
When a chemical reaction and it's reverse occur at the same time and rate the reaction is said to be?
When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about
What is the process by which chemical reactions occur that break down food molecules into energy to be used by the organism?
Breaking down of macromolecules into small particles is called a catabolic process. In any catabolic process there is a release of energy. Anabolic reaction combines small particles into a macro molecule and energy is conserved in such a process.
What increases the rate of a reaction by lowering the activation energy?
A catalyst can increase the rate of a reaction by lowering the activation energy needed for the reaction to occur. Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to happen more quickly.
