Energy-carrying molecules, such as adenosine triphosphate (ATP), are formed through the combination of electrons from chemical bonds in substrates during metabolic processes. Specifically, the electrons involved in these reactions come from the oxidation of nutrients like glucose, where electrons are transferred from carbon and hydrogen atoms to oxygen. This transfer occurs through cellular respiration or photosynthesis, ultimately leading to the synthesis of energy-rich molecules that store potential energy for use by cells.
NADP+
In Photosystem I, excited electrons are transferred to the electron carrier molecule ferredoxin. These electrons then reduce NADP+ to form NADPH, an energy-carrying molecule that is essential for the Calvin cycle in photosynthesis. This process occurs in the thylakoid membranes of chloroplasts, playing a crucial role in converting light energy into chemical energy.
Electrons typically combine with protons and molecular oxygen to produce energy-carrying molecules like ATP (adenosine triphosphate) during cellular respiration. In this process, electrons are transferred through the electron transport chain, ultimately reducing oxygen to form water and facilitating the phosphorylation of ADP to ATP. This energy is then utilized by cells for various metabolic processes.

NADP+
Electrons combine with protons from the hydrogen atom to produce an energy-carrying molecule called ATP (adenosine triphosphate) through a process known as oxidative phosphorylation in the mitochondria. ATP is the primary energy currency of the cell, providing energy for various cellular processes.

The primary energy carrying molecule in a cells is ATP. ATP is known as adenosine triphosphate which is an organic molecule that stores and releases energy, used in cellular processes.
No, an oxidized molecule has already lost electrons and is in a lower energy state. In order to gain energy, a molecule would need to be reduced by gaining electrons.

Not necessarily. The amount of energy transferred by a wire primarily depends on the current flowing through it, not just the number of electrons. The current is determined by both the number of electrons and their speed, so a wire carrying fewer electrons at a higher speed could transfer more energy than a wire carrying more electrons at a slower speed.
