In the context of photosynthesis, this proton gradient is established across the thylakoid membrane in the chloroplast. 

Explanation

The Sabatier-Senderens reaction is a hydrogenation reaction, meaning it adds hydrogen to unsaturated hydrocarbons (alkenes and alkynes) to convert them into saturated hydrocarbons (alkanes). 

Explanation

When an alcohol reacts with an alkyl magnesium halide (Grignard reagent), the product is an alkane.

The Grignard reagent acts as a strong base, removing the acidic hydrogen from the alcohol's hydroxyl group (-OH) and forming a new carbon-hydrogen (C-H) bond, thus creating an alkane.

The other product is a magnesium alkoxide salt.
