Biology
1 answer:
Firdavs [7]4 years ago
7 0

Answer: The correct answer is- C. to neutralize the acidic chyme

Bicarbonate is secreted by pancreas and released into the duodenum ( first part of small intestine) during the process of digestion.

The digestive enzymes that are secreted by the pancreas ( such as protease, amylase, lipase) into the small intestine, require an alkaline pH for their optimum functioning.

Since the chyme ( partly digested food with acidic pH, coming from the stomach) is acidic in nature, thus, the release of bicarbonate and water by the pancreas helps in neutralizing it.

This aids the final process of digestion in small intestine.

Which statement is an example of the chemical potential energy in adenosine triphosphate (ATP) being turned into work?
evablogger [386]

Answer:

The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".

Explanation:

Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
