How does NADPH get into the low form of chemical energy?
NADPH, which is reduced, is in a high form of free energy. Its low from of free energy is NADP+, which is oxidized. NADPH reaches its high state of free energy through the light reaction phase of photosynthesis. After photosystem 1 (PSI) Fd, which is an electron acceptor, reduces NADP+ turing it into NADPH by adding one proton (H+) and two electrons on to it. It is a more versatile energy source during the Calvin Cycle, the second stage of photosynthesis, than water because it has higher free energy and its energy is more accessible.

Why would molecules of gas diffuse more quickly then those of a liquid?
Gas molecules have higher kinetic energy and move more rapidly than liquid molecules. This increased speed results in gas molecules diffusing more quickly than liquid molecules, which have lower kinetic energy and are more tightly packed together. Additionally, gas molecules have more freedom of movement due to their higher energy state, allowing them to travel longer distances in a shorter amount of time compared to liquid molecules.
If a bathtub and a cup contain water at the same temperature which will have more thermal energy?
-- Temperature is the direct observation of the average kinetic energy of themolecules in the substance.-- If the tub of water and cup of water have the same temperature, then theaverage kinetic energy of the molecules in each one must be the same.-- The tub full of molecules needs more total energy than the cup of molecules does,in order to average the same for each molecule.
Do molecules move more and move apart as temp increases?
As temperature increases, kinetic energy of the molecules increases also, making the molecules move faster and move apart if they are able, as in fluids and gases.
How can you tell by looking at structure which molecules are 'most reduced' or 'most oxidized'?
The molecules that are most reduced will have the most number of hydrogens and the molecules that are most oxidized will have more oxygens around them. For example an Alkane is the most reduced followed by alkene, aldehyde, alcohol, ketone, carboxylic acid and carbon-dioxide is the most oxidized organic compound.
Would a fully oxidized or fully reduced molecule be a better cellular energy source?
A fully reduced molecule would be a better cellular energy source because it has more energy stored in its chemical bonds compared to a fully oxidized molecule. Oxidation leads to the release of energy stored in chemical bonds, while reduction stores energy in those bonds.
Why lipids have such a high energy content?
The high energy density (i.e. the relatively large amount of energy released per unit of mass) of fat stores is due to three main factors. 1) The completely reduced carbons of fatty acids have a higher energy content than the partially oxidized carbons of carbohydrates and proteins. 2) The fortuitous fact that the reduced carbons have covalent bonds to light atoms (hydrogen rather than to the heavier oxygen) means that the fully reduced hydrocarbon compounds are lighter than the partially oxidized carbohydrates. 3) Lipids are hydrophobic molecules and therefore fat stores contain little water, which would add to the weight of the molecules without adding to the energy content. Hope that helps.
What happens to a molecule when it is reduced?
A molecule is said to be reduced when one of its atoms gains an electron. Since electrons are negatively charged, the net charge of the molecule is reduced when one of it's atoms acquires an electron.
What is a reduced compound?
A reduced compound is a compound that has gained one or more electrons, resulting in a negative charge. This reduction process typically occurs during a redox reaction, where one compound loses electrons (oxidation) and another gains electrons (reduction). Reduced compounds are often considered to be in a lower energy state compared to their oxidized forms.
The more the molecules an object contain the more heat energy it has?
The heat energy of an object is related to the movement of its molecules, not the number of molecules. Heat energy is determined by the speed and kinetic energy of the molecules, rather than the quantity of molecules in the object.
The more molecules an object contains the more heat energy it has?
Yes, this is correct. The heat energy of an object is related to the average kinetic energy of its molecules. More molecules in an object means more kinetic energy overall, leading to a higher heat energy.
Why under aerobic respiration lipids have a greater energy value per mass than carbohydrates or proteins?
Lipids have a greater energy value per mass than carbohydrates or proteins because they are more reduced molecules, meaning they contain more carbon-hydrogen bonds that can be oxidized to release energy. This results in a higher energy yield during aerobic respiration. Additionally, lipids contain more energy-dense fatty acids compared to the sugars and amino acids found in carbohydrates and proteins, respectively.
What is the mechanism for this change in viscosity with heat?
As temperature increases, the kinetic energy of the molecules also increases, causing them to move more freely. This results in reduced friction between the molecules and a decrease in viscosity. Conversely, at lower temperatures, the molecules have lower kinetic energy and move less freely, leading to higher viscosity.
Is light thermal energy?
Thermal energy is not light. It is heat! Energy of heat and temperature of matter (more heat=more thermal energy=more movement of molecules) Temperature measures movement of molecules
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
How is energy related to the movement of molecules?
Energy is required for molecules to move. At higher temperatures, molecules have more kinetic energy, causing them to move faster and more freely. Conversely, at lower temperatures, molecules have less kinetic energy and move slower.
