. In which phase of cellular respiration is glucose a substrate?

vodka [1.7K]

Explanation:

During glycolysis, enzymes act on the substrate, glucose. Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.
