write the flowchart to show the breakdown of glucose by various pathways in the cytoplasm of living organisms.
Answers
Answer:
Glucose can be broken down by various pathways depending on the availability and unavailability of oxygen.
Complete Answer:
Hear the term glucose with reference to cellular metabolism and what strikes our mind is energy! Glucose is the most preferred respiratory substrate and therefore, there are many pathways that a cell can use to make sure glucose is broken down in order to obtain the ATP (adenosine triphosphate).
Generally, we use the term respiration in order to explain the metabolic process through which cells use a food source and perform its breakdown to extract out the energy.

Flowchart to show the breakdown of glucose by various pathways in the cytoplasm of living oorganism:
Hear that the term glucose refers to cellular metabolism and what comes to mind is energy! Glucose is the most preferred respiratory substrate and therefore the cell has many options to ensure that glucose is broken down to produce ATP (adenosine triphosphate).
We usually use the term respiration to describe the metabolic process in which cells use a food source and break it down for energy.
Now these pathways are primarily found by the presence and absence of oxygen. Thus, we say that a cell performs aerobic respiration when oxygen is available, because then oxygen acts as an electron acceptor at the end of the electron transport chain. When there is no oxygen, anaerobic respiration occurs.
Therefore, regardless of whether a cell performs anaerobic or aerobic respiration, a common pathway must occur to initiate the breakdown of glucose. This is called glycolysis and it takes place in the cytoplasm of the cell. The end product of glycolysis is pyruvic acid.
The glycolysis pathway is shown below. The resulting pyruvate can now follow one of three pathways:
(a)Electron transport and Krebs cycle is happen in cell when oxygen is available
b) Fermentation is also the process in the absence of oxygen
c) Lactic acid pathway in the absence supply of oxygen
