Questions Related to cellular respiration
Glycolysis is a:
-
Redox process
-
Aerobic process
-
Oxidative process
-
Reductive process
Glycolysis is a redox as well as an aerobic process. It takes place in presence of oxygen that's why this process is known as an aerobic process. In glycolysis oxidation as well as reduction takes place that's why this process is also known as redox process.
Which of the following steps of respiration is amphibolic?
-
Glycolysis
-
Oxidative decarboxylation of pyruvate
-
TCA cycle
-
Oxidative phosphorylation
The term amphibolic is used to describe a biochemical pathway that involves both catabolism and anabolism. These are the most common ways smaller organic molecules can be formed into more complex ones and applies to the formation of carbs, proteins, lipids, and nucleic acids. Other type called reduction reaction, which involves the adding of hydrogens and electrons to a molecule. it gains calories of energy because energy is released when a hydrocarbon bond is split. Pathways of glycolysis are amphibolic pathways because they provide ATP and chemical intermediates to build new cell material. The fundamental metabolic pathways of biosynthesis are similar in all organisms, in the same way, that protein synthesis or DNA structure are similar in all organisms.
Which of the following is the major regulatory enzyme of Glycolysis?
-
Hexokinase
-
phosphofructokinase
-
aldolase
-
phosphor-triose-isomerase
- In first step of glycolysis, glucose is converted in to glucose -6- phosphate by the enzyme Hexokinase or Glucokinase.
- Hexokinase is available for all cell where as Glucokinase acts only for liver cell.
- It also require magnesium as cofactor.
- Hexokinase is the major regulatory enzyme of Glycolysis.
During respiration, pyruvate is formed ________.
-
When oxygen takes part in the process
-
When oxygen does not take part in the process
-
Irrespective of oxygen taking part in the process
-
When mitochondria take part in the process
Maximum energy is released during conversion of?
-
Glucose into pyruvic acid
-
Glucose into ethyl alcohol and $CO _2$
-
Pyruvic acid into acetyl CoA
-
Pyruvic acid into $CO _2$ and $H _2O$
During the stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADP.
-
Glycolysis
-
Krebs cycle
-
Conversion of pyruvic acid to acetyl Co-A
-
Electron transport chain
Glycolysis, part of cellular respiration, is a series of reactions that constitute the first phase of most carbohydrate catabolism, catabolism meaning the breaking down of larger molecules into smaller ones. The word glycolysis is derived from two Greek words and means the breakdown of something sweet. Glycolysis breaks down glucose and forms pyruvate with the production of two molecules of ATP. The pyruvate end product of glycolysis can be used in either anaerobic respiration if no oxygen is available or in aerobic respiration via the TCA cycle which yields much more usable energy for the cell.
In glycolysis how many ATP are produced if $O _2$ is supplied?
-
$2$
-
$12$
-
$6$
-
$8$
Glycolysis pathway was invented by
-
Calvin
-
Kreb
-
J.C Bose
-
None of the above
The most common type of glycolysis is the Embden-Meyerhof-Parnas (EMP pathway), which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas.
Which is required in glycolysis?
-
ATP, ADP, $NAD^+$, Glucose, cytoplasmic enzymes
-
$FAD^+$, ADP, ATP, Glucose, cytoplasmic enzymes
-
$NADP^+$, ATP, GTP, Glucose, cytoplasmic enzymes
-
$NAD^+$, $NADP^+$, ATP, Glucose, cytoplasmic enzymes
- Glycolysis occurs in the cytoplasm of the cell and is present in all living organisms. In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid.
- Glycolysis requires specific ingredients to work. The inputs of glycolysis include a living cell, cytoplasmic enzymes, glucose, and energy transfer molecules nicotinamide adenine dinucleotide (NAD+) and adenosine triphosphate (ATP).ADP.
- Hence ATP, ADP, $NAD^+$, Glucose, cytoplasmic enzymes are required in glycolysis.
- So, the correct answer is 'ATP, ADP, $NAD^+$, Glucose, cytoplasmic enzymes'.
EMP is also known as
-
Glycolysis.
-
Krebs cycle.
-
ETS.
-
Fermentation.
Glycolysis is also known as E.M.P. pathway which stands for Embden - Meyerhof - Parnas Pathway, which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas. Glycolysis splits a 6-carbon sugar, glucose, into two molecules of 3-carbon pyruvate in a series of steps, each catalyzed by a particular enzyme. Glycolysis takes place in the cytoplasm (cytosol) of all living cells, not in mitochondria, and does not require the presence of oxygen. Therefore, glycolysis is also known as cytoplasmic respiration.
