Where do light-dependent reactions occur?

Where do light dependent reactions occur

Where do light-dependent reactions occur? The light reactions occur in the grana or thylakoid membrane of chloroplast and Involve processes that resemble mitochondrial electron Transport and oxidative phosphorylation. In photosynthetic prokaryotes, which lack Chloroplasts, the light reactions take place in the cell’s plasma membrane or in chromatophores. The photosynthesis process takes place in the chloroplast. … Read more

What are the products of light dependent reactions?

Products of light dependent reactions

What are the products of light-dependent reactions? NADPH+H and ATP are products of light-dependent reactions. This energy is used in dark reactions to produce carbohydrates. All photosynthetic animals used NADP+ H as a reducing factor.  In light-dependent reactions, light energy is converted into chemical energy. Chlorophyll and accessory pigments absorb sunlight as photons and produce … Read more

Definition Cytochromes are redox-active proteins containing a heme, with the central Fe (iron) atom at its core, as a cofactor. They are involved in the electron transport chain and redox catalysis. Cytochromes are classified according to the type of heme and its mode of binding. They are found in both animals and plants and contain … Read more

Alkaline phosphatase isoenzymes

Alkaline phosphatase isoenzymes

Alkaline phosphatase isoenzymes Alkaline phosphatase (ALP) is present in the outer layer of the cell membrane. They are present in different body tissues and have different physicochemical properties. There are six types of alkaline phosphatase isoenzymes that are isolated by electrophoresis. It is elevated in certain bone and liver diseases. ALP is useful for the … Read more



Flavoproteins Flavoproteins are made of a polypeptide bound tightly to one of two related prosthetic groups either flavin mononucleotide called FMN or flavin adenine dinucleotide called FAD.  The FMN and FAD are two coenzymes forms of riboflavin. Coenzymes are the non-protein part or compound which is necessary for the normal functioning of enzymes. FMN and … Read more
