Why is malate dehydrogenase not the best marker for mitochondria?
Because damaged mitochondria will not exhibit activity. Succinate dehydrogenase is the best option. Refer pg 32 subcellular fractionation- a practical approach.
What major events that occur during Krebs cycle?
Most summaries of the Krebs Cycle will usually indicate that the cycle is an aerobic process (one that requires oxygen) that produces ATP by breaking down glucose.Kreb Cycle shows no oxygen or glucose is used in the cycle and that it does not make much ATP (only one molecule for each acetyl CoA that enters the cycle).
Where in cell is Succinic acid dehydrogenase found?
mostly it is found in mitochondria as it is used in the TCA cycle
What is the enzyme that detoxifies alcohol?
ADH (alcohol dehydrogenase) ADH (alcohol dehydrogenase)
What are the enzymes present in mitochondria?
In outer membrane:- Monoamine oxidase, Fatty acid thiokinase, Kynurenine hydroxylase In pereimitochondrial space:- Adenylate kinase, Nucleoside diphosphokinase In inner membrane:- Succinate dehydrogenase, alpha Keto acid dehydrogenase
What is Malonic acids role with respect to succinate dehydrogenase?
Malonic acid is a competitive inhibitor of succinate dehydrogenase.
How malonate inhibit the conversion of succinate to fumarate?
Malonate is a competitive inhibitor of succinate dehydrogenase, the enzyme responsible for converting succinate to fumarate in the citric acid cycle. Malonate resembles succinate and competes for the active site of succinate dehydrogenase. As a result, malonate binds to the enzyme and prevents succinate from binding, inhibiting the conversion of succinate to fumarate.
Where does oxidative enzyme exist?
All through the Citric Acid Cycle. Succinate dehydrogenase oxidizes succinate.
Complex II of the electron transport chain?
includes a succinate dehydrogenase
Which enzyme is the most similar to Pyruvate dehyrogenase a citrate dyhydrogenase b malate dehydrogenase c succinate dehydrogenase d isocitrate dehydrogenase e alpha ketoglutarage dehydrogenase?
alpha-ketoglutarate dehydrogenase is most similar to pyruvate dehydrogenase as both are enzyme complexes made of 3 units
Which of the electron transport chain protein complexes accepts electrons from FADH2?
Complex 2 (succinate dehydrogenase)
Why is malate dehydrogenase not the best marker for mitochondria?
Because damaged mitochondria will not exhibit activity. Succinate dehydrogenase is the best option. Refer pg 32 subcellular fractionation- a practical approach.
What are marker enzymes of mitochondriya and chloroplast?
Some enzymes are present in certain organelles only; such specific enzymes are called as marker enzymes. After centrifugation, the separated organelles are identified by detection of marker enzymes in the sample. Mitochondria=> Inner membrane: ATP Synthase. Lysosome=> Cathepsin. Golgi complex=> Galactosyl transferase. Microsomes=> Glucose-6-phosphate. Cytoplasm=> Lactate dehydrogenase.
What enzyme is responsible for aerobic respiration?
There are very many enzymes involved. A few from glycolysis are: hexokinase and glucokinase, phosphohexose isomerase, phosphofructokinase, pyruvate kinase; from pyruvate decarboxylation are pyruvate dehydrogenase phosphatase and pyruvate dehydrogenase kinase; and a few from the Kreb's cycle are: aconitase, alpha-ketoglutamate dehydrogenase, succinate thiokinase, and fumarase.

The electron carrier FADH2 is produced by reactions catalyzed by which enzymes of the inner mitochondrial membrane?
Correct answer: II and III
Where is pyruvate dehydrogenase complex located in prokaryotes?
in cyptoplasm of the prokaryotic cell
