what do you understand by translocation of food in plants?explain briefly.
Answers
Answer:
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.
The benefit of transforming glucose into glucose-6-phosphate is that it will not leak out of the cell, therefore providing a one-way concentration gradient of glucose. The HPr is common to the phosphotransferase systems of the other substrates mentioned earlier, as is the upstream
The process of coupled sugar uptake with sugar phosphorylation, involving substrate modification, is called 'group translocation'. The PTS serves as a chemoreception system, directing the activity of the bacterial flagellum so that bacteria swim up concentration gradients of nutrient sugars.
