Complete oxidation of one molecule of glucose yields:

The middle step between the gaseous exchange at lung’s level and tissue level is _____.

Arrange the following in the order of their occurrence in the glycolytic pathway.

I. Triose bisphosphate $⟶$ Triose phosphate

II. Fructose-$6$-phosphate $\to$ Fructose $1,6$-bisphosphate

III. Phosphoenolpyruvate $\to$ Pyruvic acid

IV. $2$-Phosphoglycerate $⟶$ Phosphoenolpyruvate

V. Glucose-$6$-phosphate $⟶$ Fructose-$6$-phosphate

VI. Triose phosphate $⟶$ $2$-Phosphoglycerate

The correct sequence is:

Arrange the given reactions occur in electron transport in correct sequence.

$I)$ Oxygen $\to$ Removes ${\mathrm{H}}_2$ from ETS $\to$ Receives electrons form $ETS$.

$II)$ Ubiquinone $\to$ Oxidized from ubiquinol $\to$ Receives reduced equivalents from ${\mathrm{FADH}}_2$.

$III$Cyt C oxidase $\to$ Reduced by cytochrome $\mathrm{C}\to$ Electron donor for ${\mathrm{O}}_2$ to release ${\mathrm{H}}_2\mathrm{O}$.

$IV)$ Cytochrome $\mathrm{C}\to$ Mobile carrier $\to$ Transfer $e^{-}$ from cyt $\mathrm{b}$ to cyt $\mathrm{c}$ oxidase.
