Why is glucose down via many small reactions rather that all at once via one large reaction?
Glucose is broken down through many small reactions to allow for better regulation and control of energy production. This stepwise process, primarily occurring in cellular respiration, enables the cell to capture and store energy in manageable amounts, rather than losing it all at once as heat. Additionally, the gradual breakdown allows for the production of intermediates that can be used in various metabolic pathways, enhancing the cell's overall efficiency and flexibility.
What else can I help you with?
What reaction is the most spontaneous?
The most spontaneous reaction is typically a reaction that releases a large amount of energy in a short period of time, such as explosions or combustion reactions. These reactions occur quickly and without requiring an external force to initiate them.
What chemical reaction formed these large molecules what reaction would be needed to break these molecules?
Large molecules are formed through a variety of chemical reactions, such as polymerization or condensation reactions. To break these molecules down, typically a hydrolysis reaction is needed, where water is used to break the bonds holding the large molecules together.
Large protein molecule that speeds up a chemical reaction?
An enzyme is a large protein molecule that functions to speed up chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific to the reactions they catalyze and can be reused multiple times.
Why is respiration an exothermic reaction?
Respiration is considered as exothermic reaction because during the process,oxidation of glucose takes place which generates large amount of heat energy.
Why is aluminum chloride used in large excess in Friedel-Crafts reactions?
To ensure there's enough of it to allow the reaction to go to completion.
Why are reactions with alkali metals not normally carried out?
this is because there might be a large and dangerous reaction.

What is a reaction in which a large amount of energy is released?
An exothermic reaction is a type of reaction where a large amount of energy is released in the form of heat. This occurs when the energy of the products is lower than the energy of the reactants, leading to a net release of energy. Examples include combustion reactions and reactions involving the formation of more stable bonds.
What type of reactions build large molecules from smaller and simpler molecules?
Anabolic reactions build large molecules from smaller and simpler molecules through processes like dehydration synthesis. These reactions require energy input to form bonds and create complex molecules used for growth, repair, and energy storage in organisms.
What is the difference between a thermodynamically favorable and a thermodynamically unfavorable reaction?
Enthalpy change is not the only consideration for whether a reaction is favorable. However, if the enthalpy change is large, it is usually the dominant factor in determining favorability. Therefore, reactions that have a large, negative tend to be favorable, because the reaction usually releases energy when it occurs. Reactions that have a large, positive tend to be unfavorable as written, because the reaction usually requires energy to occur.
What chemical reaction formed these large molecules?
Large organic molecules (macromolecules) are generally formed by condensation reactions between smaller molecules.Condensation means that a small molecule is formed from the atoms removed during the reaction. In cells, the small molecule is water, so the type of condensation reaction is dehydration.Examples:glucose + (chain of n glucose residues) forms chain of n + 1 residues + wateramino acid + (chain of n amino acid residues) forms chain of n + 1 residues + water
What is an endogenous reaction?
An endogenous reaction is a reaction that occurs within the body naturally, either as part of normal physiological processes or as a response to a specific stimulus. These reactions are intrinsic to the body's biochemistry and do not require external substances to initiate them.
Why do endothermic reactions need additional energy to keep going while exothermic reactions don't?
Ipso facto. An endothermic reaction "absorbs" energy (uses it to create high-energy bonds), so this must be constantly supplied from an external source. An exothermic reaction "releases" energy, and this energy can be used to continue the reaction until there are no reactants remaining.This is why stellar cores cannot fuse massive quantities of elements heavier than iron. The reactions are not self-perpetuating as they are absorbing energy rather than releasing it. A large, inert iron core is the result.
