Question

The correct sequence of anaerobic respiration -
A) Glucose → pyruvate → lactic acid
glucose → pyruvate → carbondioxide + ethanol
C) glucose → pyruvate → ADP→ lactic acid
D) glucose -→ pyruvate → carbondioxide + ethanol + energy

Answer 1

correct answer ----------glucose -→ pyruvate→ carbondioxide + ethanol

explainlation =

some types of cells are release energy through the process of fermentation . fermentation includes glycolysis (responsible for synthetic of two molecules of pirate acid from one molecules of hexose sugar like glucose ) , but not the other part of aerobic cellular respiration .in fermentation glycolysis is followed by one of two Pathways : the pirate formed breaks down to become either lactate or alcohol depending on the organism . in higher animals like vertebrates when muscles work hard they need more oxygen than the body can deliver as the oxygen runs out mitochondria action shuts down in cytoplasm however brightest continue to break down glucose into pirate molecules in the absence of oxygen the pirate molecules break down to form lactate microorganism carry out a different types of fermentation many food are available because of the process of fermentation carried out by microorganisms many different bacteria are responsible for the flavours of different cheese in which their fermentation produce lactate gist also break down sugar by fermentation but the end product are carbon dioxide and ethanol this type of fermentation all of us to produce wine from grapes for example the fermentation of grains has traditionally been used to make Beer.more recently it is also given as new fuels for our internal combustion engines replacing the need for gasoline from fossil fuels hope it helps full to you

Answer 2

(B) Glucose → pyruvate → carbondioxide + ethanol is the correct sequence of anaerobic respiration.

Explanation:

• Many cells can still create ATP via glycolysis in the absence of oxygen. Fermentation and anaerobic respiration are two methods for accomplishing this.
• The electrons and hydrogen ions from the NADH produced by glycolysis are transferred to another organic molecule during fermentation.
• In yeast cells, anaerobic respiration occurs when glucose is glycolytically converted to pyruvic acid in the cytoplasm, followed by conversion to ethanol and carbon dioxide in the same location.
