both 2 & 3 utilizes ATP. Am i right ?
Sir pls solve my doubts.
Q1-Photosynthesis is maximum in which light ?:
as in ncert it is given that photosynthesis is at its peak in blue and red light so, i am confused which one of the above answer is correct.
Q2- Which of the following can photosynthesize at low temp.?
Q3-Number of carboxylation occur in Calvin cycle, is ?
Pls explain!! as the answer given in book was option(c) but i think it should be option(b) as carboxylation occurs once, when RUBP uses CO2(of atmosphere) in presence of RUBISCO to form 3-PGA.
Q4-The first step in photosynthesis is?
(a) formation of atp
(b)ionisation of water
(c)excitation of an electron of chlorophyll by a photon of light
(d)attachment of CO2 to H+ ion.
Q5-During daylight hours, the rate of photosynthesis is higher than that of respiration and the ratio of oxygen produced to that of consumed is?(a)1:1
Q6-C4 plants are found among:(a)Graminae only
(d)Monocots and Dicots
sir DCMU prevents funtioning of Plastoquinone i.e from PQ-A to PQ-B and since, PQ is found in between the non- cyclic photophosphorylation when electron goes from PS-II and PS-I
so, dcmu should inhibit PS-II right? but the answer is option B. pls explain!!!
why the answer is option A. please explain sir.
