Answer:
-Due to acidic pH of stomach.
Explanation:
Enzymes are generally made up of protein molecules and work at an optimum pH and temperature. This is because at change in pH and temperature leads to denaturation of proteins that cause change in active site of enzyme.
For trypsin, optimum pH is slightly basic as pH (7.5). So, trypsin would become non-functional at acidic pH due to denaturation and loss of active site.
Trypsin is a pancreatic enzyme that works at small intestine as pH of small intestine is slightly basic.Thus, if the trypsin was secreted in stomach instead of pancreas, it would be non-functional as stomach has acidic pH due to stomach acid.
The right answer is C. Breaking the bonds in a monosaccharide.
This phenomenon is called glycolysis.
Glycolysis is a catabolic way of transforming glucose (monosaccharide) into energy.
Glycolysis is an energy-releasing process taking place in the cytoplasm of all cells, during which glucose is degraded to provide energy. The first steps require an investment of two molecules of ATP, but the following steps will produce four.
Answer:
The correct option is <u>A. It will soon start to grow.</u>
Explanation:
In biological terms, a food chain can be described as a linear representation of energy flow in an ecosystem. It usually starts with the producers and then represents a chain until the decomposers.
A change in any of the species population of the food chain can affect the food chain widely. For example, in the question above, <em>as the population of algae increases, the population of minnows will also increase. This is because there will be more supply of food for the minnows.</em>
Answer: Point source
Explanation:
An exotoxin is a toxic substance secreted by bacteria. The botulism exotoxin is the exotoxin secretes by bacterial strain named as Clostridium botulinum.
Point source outbreak is a condition in which people are exposed to the same source of infection from a pathogen. This may occur due to the consumption of a single meal which is being infected by the pathogen. This may lead to incidences of food poisoning, disease and even mass death.
