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.
In the Calvin Cycle, the molecule that is reduced is carbon dioxide (CO2).
When NAD is reduced, the resulting molecule formed is NADH.
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
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.
Simply put, the process of oxidation is that of reacting to add oxygen. Carbon (C) burning in air (O2) to form Carbon Dioxide (CO2) is and Oxidation reaction. Conversely, the process of removing oxygen form a molecule is a reduction. When a lump of iron ore is heated with carbon, oxygen is removed and metallic Iron is produced and the Iron ore is said to have been reduced.
It gain the electrons
In the Calvin Cycle, the molecule that is reduced is carbon dioxide (CO2).
When NAD is reduced, the resulting molecule formed is NADH.
When a molecule gains an electron, it has been reduced.
When a molecule of NAD+ gains a hydrogen atom to become NADH, the molecule is reduced. Reduction is the gain of electrons by a molecule, which is what occurs in this process. This is part of a redox (reduction-oxidation) reaction where one molecule is reduced (NAD+) and the other molecule is oxidized (loses electrons).
When a molecule of nicotinamide adenine dinucleotide gains a hydrogen atom, it becomes NADH (reduced form of NAD+). NADH is a key molecule involved in carrying electrons during cellular respiration to generate ATP.
Water IS a polar molecule.
What happens to the quick return ratio when the stroke length is reduced?
nad+
Chemically, reduced means that electrons are taken on to the molecule or atom. Opposite of oxidation; stripping of electrons.
The radius is also reduced by half
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
