PGA, the first carbon dioxide fixation product was firstly discovered in

Imagine a scenario where a plant's light-dependent reactions are functioning perfectly, but the Calvin cycle is not producing glucose. A deficiency in which of the following would MOST LIKELY be the cause?

In the $C_4$ photosynthetic pathway of sugarcane, the primary product of $CO_2$ fixation is:

The oxygenation activity of ${\rm{RuBisCo}}{\rm{.}}$ enzyme in photorespiration leads to the formation of

I. In ${C_3} -$ plant, Calvin pathway takes place in mesophyll cell

II. In ${C_4} -$ plant, Calvin pathway takes place in the mesophyll cell

Which of the following statements true?

Choose the correct option

During the experiment in laboratory, the thylakoid is some how punctured so that the interior of the thylakoid is no longer separated from stroma. This damage will have the direction effect on

The synthesis of one molecule of glucose during Calvin cycle requires

PEP carboxylase

I. is involved in atleast some $C{O_2}$ fixation in both ${C_3}$ and ${C_4} -$ plants

II. Catalyses the reaction of fixing $C{O_2}$ into pyruvic acid in bundle sheath cells

III. is capable of fixing $C{O_2}$ more efficiently at lower atmospheric $C{O_2}$ concentration than RuBP carboxylase

Select the correct option

In ${C_3}$-plants, the first stable compound formed after carbon dioxide fixation is

I. In photosynthesis, the proton accumulation is towards the inside of membrane of thylakoid

II. In respiration, proton accumulation occurs in the inter membrane space of the mitochondria

Select the correct option

Which of the following is not related to photorespiration?
