What else can I help you with?
What vegetable contains the most catalase?
All fruits contain catalyse. Catalyse is found in all living things except Bactria and fungus. so all fruits and veggies have it all though when testing catalyse in those different fruits it is not always immediately evident.
Is E aerogenes aerobic?
E. Coli can be but only in oxygen free conditions. Normally it is aerobic.
What is the reaction result for the methy red test for glucose on Staphylococcus epidermidis?
In my microbilogy lab, it was Glucose negative (meaning no gas or acid produced.) We used Phenol Red, however.
Do all proteins have catalytic properties?
No, generally proteins have not catalytic properties, typical roles of proteins are - Components of the body structure (muscles for example); - Element of information transmission among cells; - Transportation proteins (like Cholesterol for example that is used tot transport fat molecules in blood) - Antibodies and many others A particular class of proteins however do exist, enzymes, that are the most used catalytic substances in nature. They are however only a particular category among proteins.
What is a substrate in the context of enzyme reaction?
Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.
Is tryptophanase a exoenzyme?
No, tryptophanase is an endoenzyme, meaning it acts on a substrate within the cell where it is produced rather than outside the cell. It catalyzes the breakdown of tryptophan into indole, pyruvate, and ammonia.
How can you tell amylase is an exoenzyme and not an endoenzym?
Endoenzymes work inside a cell. Exoenzymes work outside a cell after being secreted. Amylase is an exoenzyme because it's function is to break down starches in the mouth and GI tract. If it were an endoenzyme it would not function in this capacity.
Is lipase exo- or endoenzymes?
Lipase is an exoenzyme, which means it acts outside the cell that produces it. It functions to break down lipids into fatty acids and glycerol.
Would urease be considered an exoenzyme?
yes
What two groups of bacteria can be differentiated with the catalase test?
The two groups of bacteria that can be differentiated with the catalase test are catalase-positive bacteria, which produce the enzyme catalase and can break down hydrogen peroxide into water and oxygen, and catalase-negative bacteria, which do not produce the catalase enzyme. This test helps in distinguishing between different types of bacteria based on their ability to produce catalase.
What may be the uses of amino acids produced in gelatin hydrolysis by the pathogens that secrete this exoenzyme?
what may be the uses of amino acids produced in Gelatin hydrolysis by the pathogens that secrete this exoenzyme
Why salmonella typhi is catalase positive?
it should test + for catalase but Salmonella isolates are moderate catalase reactors.
Is the Ebola virus a toxin or exoenzyme?
No it is a virus, (as it's name suggests).An exoenzyme is an enzyme that is secreted by a cell and that works outside of that cell.A toxin is a poisonous substance produced by living cells or organisms
What enzyme distinguishes staphylococci from streptococci?
The enzyme catalase distinguishes staphylococci from streptococci. Staphylococci produce catalase, which breaks down hydrogen peroxide into water and oxygen, while streptococci do not produce catalase. This difference in catalase production allows for a simple biochemical test to differentiate between these two bacteria.
Where do exoenzyme function inregard to the bacteria inside or outside the cell?
inside
Where is catalase found apart from the liver?
Catalase is also found in potatoes
Is veillonella catalase positive?
Yes, Veillonella is catalase negative.
