WebOct 12, 2024 · Explain Hatch – Slack pathway. Answer: 1. M. D. Hatch and C. R. Slack while working on sugarcane found four carbon compounds (dicarboxylic acid) as the first stable product of photosynthesis. 2. It occurs in tropical and sub-tropical grasses and some dicotyledons. 3. The first product of this cycle is a 4-carbon compound oxaloacetic acid. WebThe Hatch-Slack Pathway is important where in order to conserve water, the pores of tropical leaves are very small. tropical zones. ... Explain how the relationship of the mesophyll cell and the bundle-sheath cell help to regulate the Calvin cycle.
The Discovery of C4 Photosynthesis – CSIROpedia
WebC4-Dicarboxylic Acid Pathway (Hatch Slack Pathway, C4 Pathway): It was worked out by Hatch and Slack (1965, 1967). However, initial discovery was made by Kortschak (1965) who found that labelled carbon dioxide ( 14 CO 2) assimilated by Sugarcane leaves first appeared in a 4-carbon compound oxalo-acetic acid (OAA or oxaloacetate). Because of … WebDifference # Hatch-Slack Cycle (C4 Cycle): 1. Hatch-Slack Cycle operates in C 4 plants only. 2. Hatch-Slack Cycle has a faster rate of CO 2 fixation. 3. Fixed CO 2 is released back in bundle sheath cells where it is finally fixed and reduced by Calvin cycle. 4. The primary acceptor of CO 2 is PEP, a 3-carbon compound. university of louisville reach

WebCorrect option is D) HSK pathway or Hatch-Slack pathway is a cyclic process. It occurs in chloroplasts. It was discovered by two Australian scientists Hatch and Slack. It is also known as C 4 pathway because it is found in C 4 plants. Most of the plants that are adapted to dry tropical region are known as C 4 plants. WebNov 30, 2024 · Hatch-Slack Pathway was first discovered by M. D. Hatch and C. R. Slack in 1966. Nearly 200200 billion tons of carbon dioxide is fixed every year in biomass. The … Web2. Hatch and Slack pathway or C4 cycle Calvin cycle or C3 cycle It is a cyclic reaction occurring in the dark phase of photosynthesis. In this reaction, CO 2 is converted into sugars and hence it is a process of carbon fixation. The Calvin cycle was first observed by Melvin Calvin in chlorella, unicellular green algae.
