Why do all enzymatic reactions need activation energy?
Activation energy is required to initiate a reaction by breaking bonds in the substrate molecules. This energy is necessary to overcome the energy barrier and trigger the reaction to proceed. Once the reaction is initiated, the catalytic action of the enzyme can lower the activation energy required for subsequent steps in the reaction.
Where does the energy from nuclear reactions come from?
Damaged Power Plants
Where does the light- dependent come from?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts. This is where chlorophyll and other pigments absorb light energy and convert it into chemical energy in the form of ATP and NADPH. This energy is then used in the light-independent reactions to produce glucose.
What does energy come from to make nadaph in light reactions?
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
What is the relationship between energy and chemical reaction?
Energy plays a crucial role in chemical reactions, as it is required to break bonds in reactants and form new bonds in products. This energy can come in the form of heat, light, or electricity, and the overall change in energy during a reaction determines whether it is exothermic (releasing energy) or endothermic (absorbing energy). Additionally, the activation energy barrier must be overcome for a reaction to proceed, highlighting the interplay between energy and the reaction dynamics.

Where does the energy come from to make nadph in the lighte reactions?
from energy used in light.
Where does the energy from nuclear reactions come from?
Damaged Power Plants
Where does the energy come from in nuclear reactions?
The energy in nuclear reactions comes from the splitting or combining of atomic nuclei, which releases a large amount of energy in the form of radiation and heat.
Where does the energy come from to make at in the light reactions?
From the motion of the hydrogen ions
Do bacteria rely on energy from reactions of inorganic sulfur compounds that come from the ocean floor?
No.
What Energy resources that don't come from the sun?
Geothermal energy, which comes from the heat within the Earth's crust, and nuclear energy, which is generated from the splitting of atoms in nuclear reactions, are two examples of energy resources that do not come directly from the sun.
What term is specific to reactions in which simple compounds are combined into more complex?
The term specific to reactions where simple compounds combine to form more complex molecules is called a synthesis or combination reaction. In this type of reaction, two or more reactants come together to form a single product.
How does bond formation release energy in chemical reactions?
Bond formation releases energy in chemical reactions because when atoms come together to form bonds, they release energy that was stored in their chemical bonds. This energy is released as heat or light, making the reaction exothermic.
Where does the energy come from to make NADPHin the light reactant?
The energy to make NADPH in the light reactions of photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, which triggers a series of reactions that ultimately produce NADPH.
Where does the light- dependent come from?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts. This is where chlorophyll and other pigments absorb light energy and convert it into chemical energy in the form of ATP and NADPH. This energy is then used in the light-independent reactions to produce glucose.
How is energy changed by reactions in a chloroplast?
Okay well think of what the chloroplast does. And where does the energy come from in the cell? okay now put two and two together and you have you're answer.
