What are the 2 steps phases of photosynthesis?

While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.

What is PEP in c4 plants?

PEP carboxylase, which is located in the mesophyll cells, is an essential enzyme in C4 plants. In hot and dry environments, carbon dioxide concentrations inside the leaf fall when the plant closes or partially closes its stomata to reduce water loss from the leaves.

Is PEP an enzyme?

EC no. 1.31, PDB ID: 3ZGE) is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO3−) to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate: PEP + HCO3− → oxaloacetate + Pi.

Where does the second stage of photosynthesis occur?

stroma
The second stage of photosynthesis takes place in the stroma surrounding the thylakoid membranes of the chloroplast. The reactions of this stage can occur without light, so they are sometimes called light-independent or dark reactions.

What are the two stages of photosynthesis and where does each one occur in the chloroplast quizlet?

The two stages of photosynthesis are light reactions and the Calvin Cycle. Light reactions occur within the thylakoids and the Calvin Cycle takes place in the stroma. The light reactions create ATP and NADPH, which are used by the Calvin Cycle which also brings in carbon to produce sugar.

What are the two stages of photosynthesis and where does each one occur in the chloroplast?

The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
