In the sieve elements,which one of the following is the most likely function of $P-$ proteins?

Choose the correct statements:
$(i)$ The complete combustion of glucose,which produces $CO_2$ and $H_2O$ as end products,yields energy,most of which is given out as heat.
$(ii)$ The scheme of glycolysis was given by Gustav Embden,Otto Meyerhof,and $J$. Parnas and is often referred to as the $EMP$ pathway.
$(iii)$ In glycolysis,$ATP$ is utilised at $2$ steps,not $4$.
$(iv)$ In both lactic acid and alcohol fermentation,not much energy is released; less than $7$ percent of the energy in glucose is released and not all of it is trapped as high-energy bonds of $ATP$.
$(v)$ For aerobic respiration to take place within the mitochondria,the final product of glycolysis,pyruvate,is transported from the cytoplasm into the mitochondria.

Differentiate between Glycolysis and Citric acid cycle.

Distinguish between the following: (Any two)
$(a)$ Aerobic respiration and Anaerobic respiration
$(b)$ Glycolysis and Fermentation
$(c)$ Glycolysis and Citric acid Cycle

During a state of rest,the metabolic requirement is very low. This can be determined by:

What is the relationship between $CO_2$ concentration and the rate of respiration?
