Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane is directly responsible for the generation of ATP during photosynthesis. It involves the movement of protons across the thylakoid membrane to create a proton gradient, which drives the synthesis of ATP by ATP synthase enzyme.
Where does the Light (dependent) reaction take place?
The light dependent reaction take place in the thylakoid of the chloroplast
What is the difference between oxidation and hydrolysis?
Oxidation is a reaction in which an atom, molecule or compound loses an electron. OIL = Oxidation Is Lost; RIG= Reduction Is Gain LEO = Lose Electron in Oxidation; GER = Gain Electron in Reduction (LEO the lion says GER) Hydrolysis is a reaction in which a molecule or compound is broken down, by the addition of a water molecule (it is NOT the breaking of a water molecule into oxygen and hydrogen - that is a different reaction called electrolysis). An example of hydrolysis is the breaking down of maltose into 2 glucose molecules. A molecule of water is added, usually with an acid to catalyse the reaction, into a solution of maltose. You can therefore say that hydrolysis is a type of oxidation reaction, being as maltose loses glucose molecule (hence losing the electrons in the atoms of glucose).
In the light reaction what is the electron donor where do the electrons end up?
water donates the electrons when H2O is separated into 2 hydrogen and one oxygen by the water-splitting enzyme in photosystem II. The electrons then enter the electron transport chain, entering a hydrogen pump which uses energy to push hydrogen into the thylocoid. Electrons get recharged in the next chlorophyll almost like a battery, finally they combine with NADP+ and a hydrogen to create NADPH. btw, two electrons are donated per H2O molecule
How does light and dark reactions takes place?
The light dependent reaction occurs in the chloroplast. In the light dependent reaction, chlorophyll pigments absorb solar energy. This energy is then converted into a chemical form (not glucose). The water molecule is split into oxygen and hydrogen molecules. The dark reaction or the carbon fixation period occurs in the fluid matrix or stroma of chloroplast. The hydrogen product from the first reaction is combined with the carbon dioxide molecules to makes sugars. This results in the C3 or C4 cycle.
One gold sulfate molecule reacts with three hydrogen molecule to make hydrogen sulfate and gold A gold sulfate molecule includes two gold atoms How many gold atoms will be present after this reaction?
hydrogen is not a molecule.
What role does a molecule play as a hydrogen bond acceptor or donor in chemical reactions?
In chemical reactions, a molecule can act as a hydrogen bond acceptor by accepting a hydrogen atom from another molecule, or as a hydrogen bond donor by donating a hydrogen atom to another molecule. This interaction helps stabilize the molecules involved in the reaction.
When a glucose molecule loses a hydrogen atom as the result of an oxidation-reduction reaction the molecule becomes?
oxidized
Where is the light reaction?
On thylakoid membranes

Does the heat of neutralization reaction depend on the number of hydrogen atoms in a molecule of acid?
No. The rate of the neutralization reaction is concentration dependent, but the "heat of neutralization" is defined on a molar basis already, so it is not.
Where does the light reaction happens?
Light reactions occur in the cells chloroplast
When hydrogen is added to ch3ch2chchch3 the reaction is an?
... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane. --- ... known as hydrogenation.
What is the first stage of the thylakoid reaction?
Primary photoevent.
Why the reaction between hydrogen and chlorine is very slow at room temperature?
The reaction between hydrogen and chlorine is slow at room temperature because it has a high activation energy barrier that needs to be overcome for the reaction to occur. This barrier is attributed to the stability of the chlorine molecule and the absence of external energy sources to provide the necessary activation energy at room temperature.
When the reaction center for photosystem II loses and electron how is the electron replaced?
It comes from H20, the Oxygen molecule joins with another 0 molecule to form 02, the H+s enter the thylakoid space from the stroma
What kind of chemical reaction is H2 O2 H2O2?
This reaction is a decomposition reaction, where hydrogen peroxide (H2O2) breaks down into water (H2O) and oxygen gas (O2) as a result of the breaking of chemical bonds within the hydrogen peroxide molecule.
