Answer:
they help lower the activation energy of chemical reactions
The given question is incomplete, the complete question is:
One of Loraine's friends, Marie, started purchasing raw, unpasteurized milk for her children. Marie insists that pasteurization reduces the nutritional quality of milk and raw milk contains phytochemicals that are destroyed during pasteurization. What should Loraine tell her friend about pasteurization?
A: The pasteurization process heats foods to kill pathogenic microorganisms and reduce the total number of bacteria.
B: The pasteurization process denatures protein and kills harmful prions.
C: The pasteurization process evenly distributes fat particles throughout the milk so the cream doesn't rise to the top of the milk.
D: The pasteurization process releases bound calcium and increases absorbable dietary calcium in cow's milk.
Answer:
The correct answer is option A, that is, by the process of pasteurization food is heated in order to eliminate the pathogenic microbes, which eventually diminishes the bacterial number.
Explanation:
The process by which some of the components of food like dairy products and juice are heated slightly so that the harmful bacteria and pathogens get eliminated from the food is known as pasteurization. It is important to kill such bacteria and pathogens as it may cause certain diseases after consumption.
Pasteurization is the process of treating non-packaged and packaged foods with a mild heat, which is generally less than 100 degree C. The process helps in extending the shelf-life of the food product by eliminating the harmful bacteria and pathogens from it.
Answer:
The change is not a physical change because a new chemical is formed on the outside of the statue.
The skeletal muscle is used, so A.
Answer:
On the exterior of the cell.
Explanation:
The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.
In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.
After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.
