What are two advantages of glycolysis

Answers

Glycolysis, the initial stage of cellular respiration, offers several advantages essential for cells' energy production and survival. Two significant advantages are Efficiency and Substrate availability.

1. Efficiency: Glycolysis occurs in the cytoplasm and does not require oxygen, making it an anaerobic process suitable for cells in low-oxygen environments.

It rapidly converts glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

2. Substrate availability: Glycolysis uses glucose, a simple sugar readily available from various sources like carbohydrates.

This flexibility allows cells to obtain energy from different nutrient molecules, ensuring a continuous supply of substrates for energy production even when other energy sources are limited or unavailable.

Glycolysis plays a fundamental role in sustaining cellular energy needs under diverse conditions.

The statement which is not true about observation is as follows:

  • Observations are foolproof and should always be trusted or believed.

Thus, the correct option is A.  

What is Observation?

Observation may be defined as the process of analyzing or monitoring some activities that are performed either by you or others to interpret the outcome.

Some of the observations are not always true, and hence they can not be trusted or believed immediately.

Such observation required the action of modification and then can be observed cautiously with full concentration in order to eliminate some mistakes.

Therefore, the correct option for this question is A.
