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.
Answer:
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Answer:
Percentage of glucose that is returned to the muscles.
Explanation:
After intense physical activity, where glycogen reserves are consumed, the muscle acquires its resting and reactivation position, is where the organism that feeds the new reserves for the next physical activity is located.
Foods rich in carbohydrates identified as ATP or glucose in good quantities, but this depends on the amount of intake and the quality of the food, that is how when consuming these sources, the serum glucose values are metabolized, that is, increases glycemia and this promotes the release of insulin that is responsible for generating energy reserves with more complex chemical bonds such as glycogen.
Answer:
The correct answer is option A. "Culture B will have more colonies on the histidine-minus plate than culture A".
Explanation:
In this example, Culture B is a culture of E. coli that has been exposed to a mutagenic agent, therefore it has the potential of developing bacteria that by chance, is able to live in a medium lacking histidine. On the other hand, Culture A is the same E. coli culture but without the exposure to the mutagenic agent. The expected result is that Culture B will have more colonies on the histidine-minus plate than culture A, illustrating that a mutagenic agent can produce E. coli able to reproduce in a histidine-minus plate.
