Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:
1. Absorbed CO2 is added to RuBP and 6C sugar is formed.
2. Breaking of 6C sugar into two 3-phosphoglycerate molecules
3. ATP gives phosphate group to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.
4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH
5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called fructose-1,6-biphosphate which is further converted to fructose-6-phosphate
6. Enzyme isomerase converts fructose-6-phosphate to glucose-1-phosphate
<span>The elements that are found in a high proportion in Earth's crust are oxygen, aluminium, iron, calcium, potassium, sodium, and magnesium. But for your Option, I think it is B) Oxygen and Silicon. This is because Oxygen makes 46.6% while Silicon makes 27.7% of the Earth crust.</span>
<span>Evidence about ancient climates indicates that
</span>glacial ice once covered much of what is now India and Australia
There was once glacial where these countries are located now due to heat it all melts
so correct option is A
hope it helps
An energy pyramid illustrates that energy in the form of heat is lost to the surrounding as it is passed from one organism to the next. In an energy pyramid energy is passed from one trophic level to the next, however, only ten percent of the energy in a given trophic level is passed to the next, as most of the energy is lost inform of heat to the surroundings.
