Electrons are both gained and lost. Electrons are both gained and lost.
In an electrochemical cell, oxidation occurs at the anode, where electrons are lost as a result of a redox reaction. The anode is where oxidation half-reactions take place, generating electrons that flow through the external circuit to the cathode. Reduction, on the other hand, occurs at the cathode, where electrons are gained during the redox reaction. This flow of electrons from anode to cathode is what generates an electric current in the cell.
The type of reaction in which the gain of an electron takes place is called a reduction reaction. In a reduction reaction, a reactant gains electrons, thereby reducing its oxidation state. This process is often coupled with an oxidation reaction, forming a redox reaction.
It takes place on thylokoid membranes.Dark reaction takes place in stroma.
In the light reaction phase of photosynthesis, light energy is converted into chemical energy in the form of ATP and NADPH. These energy carriers are then used in the dark reaction phase, also known as the Calvin Cycle, to convert carbon dioxide into glucose. The dark reaction does not require direct light and takes place in the stroma of the chloroplast.
When Bordeaux mixture is mixed with iron, a redox reaction takes place where iron reduces copper(II) ions in the Bordeaux mixture to copper(I) ions. This reaction ultimately leads to the formation of a dark reddish-brown precipitate known as copper(II) oxide.
An oxidation half-reaction
An acid and an alkali/base takes place in a neutralization reaction. For reactions such as redox, precipitation etc. an acid or a base might not take place.

Everywhere if you refer to redox chemical reaction. Every organ uses redox reactions to transform something into something else. Brain for instance transforms glucose.
The process is called cellular respiration. It takes place in mitochondria

It takes place in thylokoids.Dark reaction is in stroma
they make it easier to see the oxidation and reduction parts of the reaction separately.
When HCl is added to sodium thiosulfate, a redox reaction takes place, resulting in the formation of solid sulfur (S) and sodium chloride (NaCl) in solution. Additionally, the reaction produces sulfur dioxide gas (SO2) and water (H2O) as byproducts.
It takes place on thylokoid membranes.Dark reaction takes place in stroma.
Mainly it is a hydrolysis. It releases a water molecule
The reaction between lemon juice (containing citric acid) and potassium permanganate is a redox reaction. The purple color of the potassium permanganate fades as it gets reduced to colorless manganese(IV) oxide, while the citric acid gets oxidized to carbon dioxide and water. The reaction is exothermic and can be used to demonstrate redox reactions in chemistry experiments.
