Select the option with incorrect pair of differences between alcoholic fermentation and lactic acid fermentation.

 

Alcholic fermentation

Lactic acid fermentation

(i) Takes place in a single step Takes place in two steps
(ii) Releases CO2 Does not relaese CO2
(iii) Produces ethyl alcohol in plants and most microganisms Occurs in certain bacteria, some fungi and verterbrate muscles
(iv) Does not form any intermediate compound Forms acetaldehyde as an intermediate compound

MEDIUM
Which of the following statements is incorrect?
MEDIUM

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

I) Oxygen Removes H2 from ETS Receives electrons form ETS.

II) Ubiquinone Oxidized from ubiquinol Receives reduced equivalents from FADH2.

III Cyt C oxidase Reduced by cytochrome C Electron donor for O2 to release H2O.

IV) Cytochrome C Mobile carrier Transfer e- from cyt b to cyt c oxidase.

EASY

Assertion (A) :- The pathway from glucose to lactic acid occurs in 10 metabolic steps. Organisms will trap this energy and store in the form of chemical molecules.

Reason (R) :- Glucose is the only substrate for the production of energy.

The correct option among the following is:

MEDIUM

Assertion (A): When electrons move through the transport chain, protons are transported across the membrane.

Reason (R) : Because the primary acceptor of electron located towards the outside of the membrane, transfers its electrons to a H carrier (PQ). 

The correct option among the following is:

MEDIUM
