Where did Melvin Calvin grow up?
Melvin Calvin was born in St. Paul, Minnesota, on April 8, 1911, to Russian immigrant parents. The family moved to Detroit, Michigan when Calvin was a child.
What did Melvin Calvin get a Nobel Prize for?
The Nobel Prize in Chemistry 1961 was awarded to Melvin Calvin “for his research on the carbon dioxide assimilation in plants.”
How did Calvin discover Melvin Calvin cycle?
Calvin shone light on the lollipop and used a radioactive form of carbon called carbon-14 to trace the path that carbon took through the algae’s chloroplast, the part of the cell where photosynthesis occurs. By this method, he discovered the steps plants use to make sugar out of carbon dioxide.
Where did Melvin Calvin go to college?
Melvin Calvin was born in St. Paul, Minnesota, April 8, 1911, of Russian emigrant parents. He received the B.S. degree in Chemistry in 1931 at the Michigan College of Mining and Technology, and the Ph.
Who discovered dark reaction?
NADPH and ATP drive the second stage, the “dark” reactions (or Calvin cycle, discovered by Melvin Calvin), which do not require light. During this stage glucose is generated using atmospheric carbon dioxide. The light reaction of photosynthesis.
What University did Calvin and Benson go to?
the University of California Berkeley
Through his work in the 1940s and early 1950s with chemist Melvin Calvin at the University of California Berkeley, Dr. Benson discovered the pathway of carbon dioxide in photosynthesis, a mechanism that became known as the Calvin-Benson cycle.
What was Melvin Calvin famous for?
Melvin Calvin, (born April 8, 1911, St. Paul, Minnesota, U.S.—died January 8, 1997, Berkeley, California), American biochemist who received the 1961 Nobel Prize for Chemistry for his discovery of the chemical pathways of photosynthesis.
What is Calvin cycle Class 11?
What is Calvin Cycle? Calvin cycle is also known as the C3 cycle. It is the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars. It occurs in the chloroplast of the plant cell.
What are Grana?
Grana are the sites for the light reaction of photosynthesis. The grana of the chloroplast are disc-like plates, which consist of a pigment system made up of chlorophyll-a, chlorophyll-b, carotene and xanthophyll.
Is chlorophyll A?
Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light, and it is a poor absorber of green and near-green portions of the spectrum….Chlorophyll a.

What role do grana play?
The Function of Grana in Plants. The major function of grana is to conduct the photosynthesis process. Grana (thylakoid membrane to be exact) is the site where light reactions of photosynthesis occur.
Who discovered C3 and C4 pathway?
It was discovered by two Australian scientists Hatch and Slack. It is found in C4 plants. Carbon dioxide fixation is done in this pathway. The primary CO2 acceptor is a three-carbon molecule phosphoenolpyruvate (PEP) and it is present in mesophyll cells.
Who discovered CAM pathway?
The term CAM may have been coined by Ranson and Thomas in 1940, but they were not the first to discover this cycle. It was observed by the botanists Ranson and Thomas, in the succulent family Crassulaceae (which includes jade plants and Sedum).
Where does Calvin cycle take place?
stroma
Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
