In which metabolic pathway does Phosphoenolpyruvate (PEP) serve as the primary $\rm{CO_2}$ acceptor?

In ${C_4}$-pathway, the first product identified was

PEPcase catalyse primary carboxylation step in

I. Initial $C{O_2}$ acceptor

II. Extent of photorespiration

III. Enzyme catalysing reaction that fixes $C{O_2}$

IV. Presence of Calvin cycle

V. Leaf anatomy

Which one does not differ in a ${C_3}$ and ${C_4} -$ plants?

Calvin cycle is also called

Identify the enzyme which catalyses the first step of photorespiration in ${C_3}$ . plants.

Which of the following is maximum in chloroplast?

Photosynthesis and respiration are similar because

I. in eukaryotes, both processes occur in specialised organelles

II. ATP synthesis in both is explained by chemiosmotic theory

III. both use ETC

Select the correct option

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

Primary acceptor of $C{O_2}$ in ${C_4} -$cycle is

The turns of Calvin Cycle requires to form one glucose molecule
