Why is the citric acid cycle a cyclic pathway rather than a linear pathway?

Biology
1 answer:
Rama09 [41]3 years ago
3 0

The given question is incomplete as the four possible explanations or options are not provided, however, the correct options are as follows:

A) More ATP is produced per CO2 released in cyclic processes than in linear processes.

B) It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA.

C) Redox reactions that simultaneously produce CO2 and NADH occur only in cyclic processes.

D) Cyclic processes, such as the citric acid cycle, require a different mechanism of ATP synthesis than linear processes, such as glycolysis.

Answer:

The correct answer would be - option B

Explanation:

Circular pathways or the cycles are able to carry out two or more than two entry and exit points for the substrate enzyme and products, So it is well suited for amphibolic reactions.

In a linear pathway, one reaction with particular substrate or reactants  and result in products through the pathway completes the pathway, and the second reaction would be an independent event.

In citric acid cycle It is easier to eliminate electrons and gain carbon dioxide from compounds with 3 carbon or more carbon atoms than from a two-carbon compound such as acetyl CoA. pyruvate is 3 C compound while acetyl CoA is two carbon.

Thus, the correct answer is - option B

cupoosta [38]

Answer:

Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.

Explanation:

Water shed are of different types-

  1. Large water sheds-Contain well developed channel networks.
  2. Small water sheds-Contain dominant land phase.
  3. Urban watershed-It is dominated by building,roads,pavements.
  4. Agriculture water shed-
  5. Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
  6. Mountain water shed-mountain is the dominant component that separates the water flow.
  7. Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
  8. Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.
