Why is fresh pineapple not used in gelatin desserts?
Pineapples contain an enzyme that is used to aid digestion and to tenderize meat, which will not only be tender but will likely fall apart. This is the reason that fresh pineapple cannot be used in gelatin desserts as it will break down the protein in the gelatin. Since heating destroys this enzyme, gelatin desserts are successfully made using canned pineapple. Bromelain is a proteolytic (protein-dissolving) enzyme similar to papain in unripe papaya and ficin in fresh figs. It can be so strong that plantation and cannery workers must wear rubber gloves to prevent their hands from being eaten away. The enzyme has also proven to break down many harmful proteins and may well play an important role in thrombosis treatments in the future. Thrombosis is a blockage of blood vessels by clots and are responsible for a significant number of deaths each year. Heart attacks are most often the result of blockage in the blood vessels serving the heart, while strokes are the result of similar blockages in the vessels of the brain. The damage done from these clots is caused largely by a protein called fibrin, which bromelain is able to break down. Progress in this area is slow, however, as the medical establishment is still reluctant to admit that diet plays any significant part in illness or recovery. Bromelain is extracted mainly from the stems of pineapple, although it is also present in the fruit and leaves.
What is the role of sodium carbonate in protease assay?
act as stabilizer.
How can an enzyme be a catalyst?
An enzyme has the role of a catalyst but in biochemistry.
If the mitochondrion is fundmental to the mtt assay which organelle plays a key role in the neutral red viability assay and why?
The lysosome plays a key role in the neutral red viability assay. Neutral red is taken up by lysosomes and accumulates in these acidic organelles in viable cells, producing a red color. This assay measures lysosomal function as an indicator of cell viability and health.
What is the role of enzyme in cells?
enzyme sped up the chemical reaction
What role does gelatin play in the production of vitamins?
Gelatin is used as a coating for some vitamins to protect them from moisture and light, helping to extend their shelf life and maintain their potency.
What enzyme plays a role in replication?

How does adding an acid to an enzyme reaction effect the enzyme?
it alters the pH of the enzyme denaturing it leaving it unable to carry out it's role effectively or at all
What is a feature of vitamins?

What enzyme plays a major role in Calvin cycle?
Rubisco
What is the role of ubiquinone in the electron transport chain?
Ubiquinone carries electrons from the first enzyme complex to the second enzyme complex
What 3 letters in the enzyme's name tells that it is an enzyme?
The suffix -ase indicates an enzyme, e.g. proteinase, dehydrogenase, hydrogenase, polymerase.
