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

Analogy type questions:
$(1)$ Krebs cycle : Hans Krebs :: Glycolysis : ......
$(2)$ Glycolysis : Absence of oxygen :: Krebs cycle : ......

Differentiate between (Any two):
$(a)$ Respiration and Combustion
$(b)$ Glycolysis and Krebs' cycle
$(c)$ Aerobic respiration and Fermentation

How many $ATP$ molecules are produced from the complete oxidation of one glucose molecule via the $HMP$ shunt (Pentose Phosphate Pathway) (in $ATP$)?

Select the correct statement regarding microfibrils.

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.
