What does methylamine do to electron transport?
What does methylamine do to electron transport?
From experiments with methylamine and other substances, it has been discovered that the rate of electron transport is inversely proportional to the size of the pH gradient.
How does ammonium chloride affect photosynthesis?
Ammonium Chloride Increases the Rate of Reduction of DCPIP by Chloroplasts When the Reaction Is Light-saturated— 2 unequivocally show that light is not the limiting factor when photosynthetic reactions are light-saturated because the reaction rates can be increased at a given light level by adding NH4Cl.

Are chloroplasts needed for reduction of DCPIP?
In this investigation, DCPIP (2,6-dichlorophenol-indophenol), a blue dye, acts as an electron acceptor and becomes colourless when reduced, allowing any reducing agent produced by the chloroplasts to be detected….Using a micro-centrifuge.
| Time/min | Absorption Tube 1 | Absorption Tube 5 |
|---|---|---|
| 8 | 0.6 | 1.6 |
| 9 | 0.6 | 1.3 |
| 10 | 0.6 | 1.1 |
What does DCPIP stand for?
2,6-Dichlorophenolindophenol
Wikipedia. License. 2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis.
Which product of Hill reaction are used in Blackmans reaction?
Blackman’s reactions or dark reactions take place in the stroma of the chloroplast. In dark reactions, sugars are synthesized from carbon dioxide by using ATP and NADPH2, which are end products of Hill’s reaction. Thus, the correct answer is option C.
Why is DCPIP used in photosynthesis?
DCPIP is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and colourless when reduced. DPIP is commonly used as a substitute for NADP+. The dye changes color when it is reduced, due to its chemical structure.
What is thylakoid and grana?
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Grana are connected by intergranal/stromal thylakoids, which join granum stacks together as a single functional compartment.
What is the difference between grana and granum?
Thylakoids present in chloroplasts are arranged in tight sacks known as grana. Grana is plural, whereas granum is singular. Two grana are connected by stroma lamellae.
What is the Colour of Indophenol?
Indophenol is an organic compound with the formula OC6H4NC6H4OH. It is deep blue dye that is the product of the Berthelot’s reaction, a common test for ammonia. The indophenol group, with various substituents in place of OH and various ring substitutions, is found in many dyes used in hair coloring and textiles.
What is the formula for methylamine in water?
Methylamine is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine. It is sold as a solution in methanol, ethanol, tetrahydrofuran, or water, or as the anhydrous gas in pressurized metal…
What is the equation for the reaction between methylamine and sulfuric acid?
In this neutralization reaction, 2 moles of methylamine (weak base) react with 1 mole of sulfuric acid (strong acid) and generate 1 mole of a methyl ammonium salt (a salt of a weak base and a strong acid). In a similar reaction, methylamine can neutralize hydrochloric acid, another strong acid.
How is methylamine prepared in chemhack’s step by step guide?
Chemhack’s step-by-step methylamine preparation guide Preparation of a 10% Methylamine solution in methanol Methylamine from catalytic hydrogenation of nitromethane Photo-essay: Methylamine from Ammonium Chloride and Formaldehyde Methylamine Hydrochloride from Acetamide Introduction and Reaction Mechanism
What is the reactivity of methylamine in organic chemistry?
Reactivity and applications. Methylamine is a good nucleophile as it is an unhindered amine. As an amine it is considered a weak base. Its use in organic chemistry is pervasive. Some reactions involving simple reagents include: with phosgene to methyl isocyanate, with carbon disulfide and sodium hydroxide to…
