Different reactions have different metabolites which may act as energy storing molecules. For instance, in glycolysis, fructose-1,6-bisphosphate and phosphoenolpyruvate represent just two of the main energy storing molecules.

Which accounts for the increase in the rate of reaction when a catalyst is added to a reaction system. Does the entropy of the reaction increase?
When two molecules react with each other they must form a transition state. The higher the energy of the transition state the less likely it is for the two molecules to react with each other. Catalysts lower the energy of the transition state. This makes it more likely for molecules to react with one another, which speeds up the overall reaction. Entropy is unrelated. Reactions that break apart molecules increase entropy. Reactions that combine molecules together diminish entropy. Both types of reactions can be sped up by catalysts.
How is the rate of a reaction influenced by a catalyst?
The rate of reaction often increases when catalysts are added. Catalysts can either lower the activation energy required for the reaction to happen, so that means more molecules will have enough energy to react than if the activation energy were higher. Catalysts can also be like substrates that act as a site for holding the molecules in the correct position to react. Always remember that molecules need to collide in the correct position with enough energy in order to react, and so catalysts will aid these two requirements and increase the reaction rate. There are catalysts that slow the reaction, but it's not common.
How many molecules of glucose are produced by each cycle of the light reaction?
Zero
Why do you have to balance chemical equations?
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).
The smallest amount of energy needed to start a chemical reaction is called?
Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer
What happens durring a chemical reaction?
During any chemical reaction there will be a spontaneous motion of each atoms/ molecules, and all atoms/ molecules collides with each other, on each collision there will be a microscopic interaction, and, there will be a rearrangement in electronic configuration when a low energy or "symmetry" can be obtained. Due to this reconfiguration the spatial arrangement and motion of atoms/molecules changes which is what we observe.

What happens to the bonds of substance during a chemical reaction?
First chemicals bonds in the starting substances must break. Molecules are always moving. If the molecules bump into each other with enough energy,the chemical bonds in the molecules break. ;)
How do enzymes help accelerate reactions?
Chemical reactions involve collisions between molecules. most collisions don't have either the right orientation or enough energy for the reaction to proceed. the molecules just bounce off each other, unchanged. incidentally that is why reactions proceed faster as the temperature increases - high temperature means molecules are moving faster and are more likely to have the required energy to react.Enzymes are protein catalysts that force reactant molecules into the correct orientation and lower the required energy for a collision to produce a reaction.
What is the transfer of thermal energy by molecules bumping into each other?
The transfer of thermal energy by molecules bumping into each other is known as conduction. Thermal energy is energy that comes from heat.

What are the main energy storing products of each phase of photosynthesis?
It is the pigment. It is absorbing light.

What is relation of co2 to the photo chemical reaction?
photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules' absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical species can fall apart, change to new structures, combine with each other or other molecules, or transfer electrons, hydrogen atoms, protons, or their electronic excitation energy to other molecules. Excited states are stronger acids and stronger reductants than the original ground states.
How does temperature increase affect collisions between molecules?
The number of collisions with enough energy to react increases.
Why do you get a better reaction with warm or hot vinegar and baking soda?
Chemical reactions have a kinetic componant where the molecules must move around in solution and actually meet each other in order to react. Additionally they must also meet with sufficient force to provide the activation energy for the reaction. When matter is heated the particles of matter gain more kinetic energy. The hotter the vinegar is the faster the molecules are moving the greater the change of them colliding with molecules of baking soda and the greater the chance this collision will result in a reaction.
