What is the succinate dehydrogenase role in the cell?
Succinate dehydrogenase is an enzyme that plays a key role in both the citric acid cycle (Krebs cycle) and the electron transport chain. It catalyzes the oxidation of succinate to fumarate, generating FADH2 in the process. This enzyme helps in the production of ATP and is essential for cellular respiration.
What is muramic acid?
Muramic acid is a molecule found in bacterial cell walls, specifically in the peptidoglycan layer. It contains a unique structure that is absent in other organisms, making it a useful marker for identifying bacterial presence. Muramic acid plays a crucial role in maintaining the structural integrity of bacterial cell walls.
Where is the nucleic acid found in a eukaryotic cell?
Nucleic acids, specifically DNA, are found in the nucleus of eukaryotic cells. RNA, another type of nucleic acid, can also be found in the nucleus and in the cytoplasm of eukaryotic cells.
Is mycolic acid found in gram positive and gram negative cell wall composition?
Mycolic acid is primarily found in the cell walls of mycobacteria, which are a type of bacteria that include the causative agents of tuberculosis and leprosy. It is not typically found in the cell walls of other bacteria, including those classified as gram-positive or gram-negative.
What nucleic acids include?
Nucleic acids include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA carries genetic information and is found in the cell nucleus, while RNA plays various roles in protein synthesis and is found in the cell cytoplasm.
Why can a porin -deficient mutant be detected by its inability to grow on a medium containing a single carbon source such as succinic acid?
Porins are outer membrane proteins that allow the passage of small molecules, like succinic acid, across the bacterial outer membrane. In a porin-deficient mutant, the lack of porins would prevent the entry of succinic acid into the bacterial cell, impairing its ability to use succinic acid as a carbon source for growth. Consequently, the mutant would not be able to grow on a medium containing succinic acid as the sole carbon source.
Why can a porin-deficient mutant be detected by its inability to to grow on a medium containing single carbon source such as succinic acid?
Because the porin is involved in succinic acid transport into the cell...

Where is pyruvate dehydrogenase complex located in prokaryotes?
In prokaryotes, the pyruvate dehydrogenase complex is located in the cytoplasm.
What substance is not produced in a muscle cell under anaerobic conditions?
Lactic acid (also called lactate).The product of glycolysis in the cytoplasm is pyruvic acid (= pyruvate). If there is not enough oxygen for the mitochondria to oxidize the pyruvic acid, the enzyme lactic acid (or lactate) dehydrogenase, which is in the cytoplasm, reduces the pyruvic acid to lactic acid.
What is the name of the acids found in the nucleus of a cell?
Nucleic acid
What type of nucleic acid is the general material of the cell?
The general form of nucleic acid is called deoxyribose nucleic acid or DNA.
Where is ribonucleic acid in the human body?
It is found in every cell in the body.
Which nucleic acid is found inside and outside the nucleus of a cell?
RNA
Where is the cell is the DNA found?
The nucleus, or center, DNA or Dioxyribonucleic acid. The DNA is in the chrimosomes in the middle of the cell.
What are the two most common nucleic acids found in every cell?
DNA and RNA : Deoxyribonucleic acid and ribonucleic acid.
What Enzymes oxidize cell substances?
Enzymes like catalase, cytochrome P450, and alcohol dehydrogenase are involved in oxidizing cell substances. Catalase breaks down hydrogen peroxide, cytochrome P450 is involved in drug metabolism, and alcohol dehydrogenase metabolizes ethanol.
