How would you explain why bicarbonate and digestive enzymes respond differently in two of the variables in figure 30-8

Answer:

1. Response to hydrochloric acid

HCO3- also known as bicarbonate, is a polyatomic anion, a byproduct of the body's metabolism and one of the two main components of the pancreatic juice. A base excreted by the epithalial cells of the pancreas, bicarbonate has the critical function of neutralizing the hydrochloric acid found in the gastric juice. This is why the pancreatic juice contains mostly bicarbonate when this acid is present.

2. Response to fat

When fats are predominant, the second component of the pancreatic juice, the digestive enzymes are abundant. This broad group of biological catalysts have the role of reducing all digestible macromolecules (such as fats) into forms that can be absorbed by the body. They are critical to the digestive process.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
