In glycolysis the first few steps require energy from two ATP molecules. The net gain of ATP molecules at the end of this pathway is?
2 ATP molecules
What is photoactivation of chlorophyll?
The initial stage of [[photosynthesis in [[chlorophyll Molecules where the presence of [[light Energy raises the energy. It is the first event int he first phase of photosynthesis which is light-dependent reactions.it happens at the thykaloid. Chlorophyll molecules capture light energy and becomes energized electrons(e-).
The energy in food molecules such as glucose is converted into what?
Its been degraded to two molecules of pyruvate.
According to the heterotroph hypothesis what contribution did ultraviolet light heat and lightning make to the formation of the first organic molecules?
They provided energy sources.
What process breaks down glucose before cellular respiration?
Glucose is broken down IN cellular respiration, also called the Kreb cycle. Glucose enters this electron transport chain process intact, and is broken down to CO2 and water, while giving off chemical energy which is stored in the form of ATP molecules for the cell to use for chemical energy in metabolic processes. Glucose is not broken down before cellular respiration; it is broken down IN the process.
What is The first stage of the breakdown of sugar molecules for energy?
The first stage of the breakdown of sugar molecules for energy is glycolysis. The sugar molecules are broken down by enzymes, releasing energy in the process.
Do water molecules with highest energy evaporate first?
Yes, it is correct.
What potential energy does fossil fuel?
first of all thermal energy does not move it actcually gains molecules
In glycolysis the first few steps require energy from two ATP molecules. The net gain of ATP molecules at the end of this pathway is?
2 ATP molecules
What is the first thing that must occur for two molecules to react with one another?
The two molecules must collide with the correct orientation and with a minimum amount of energy (called the activation energy).
What happened to energy after it use?
It is changed into a different form of energy as it cannot be destroyed (First law of thermodynamics) usually kinetic energy of the molecules
What are two chemical reactions that are necessary to give cell energy?
This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. The first step is the enzymatic breakdown of food molecules in digestion, and the second step that converts glucose molecules is called glycolysis.
What happens to thermal energy after its use?
It is changed into a different form of energy as it cannot be destroyed (First law of thermodynamics) usually kinetic energy of the molecules

It is the first event int he first phase of photosynthesis which is light-dependent reactions.it happens at the thykaloid. Chlorophyll molecules capture light energy and becomes energized electrons(e-).
Energy used in the formation of the first organic molecules is thought to have come from?
Organic molecules form out in nature all the time by various energy sources. Organic molecules (such as amino acids and nucleobases) are found in meteorites, and many organic molecules (sugars) are found even in interstellar space.
What reactants are capable of interacting to form products in a chemical reaction that must first overcome a thermodynamic barrier?
Fast moving reactant molecules or basically reactant molecules with a lot of kinetic energy.
Do gas molecules have more kinetic energy with altitude?
The kinetic energy of molecules depends on the temperature. At first this decreases with altitude, and therefore so does kinetic energy, but then the relationship with height becomes very complex. A search for 'temperature profile of the atmosphere' will give you more details.
