Answer:
Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.
Explanation:
Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.
The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.
A because water is collected in clouds from bodies of water than falls back down as rain snow or hail
Answer:
cells
Explanation:
cells are responsible for the structures and functions
The usual way of reading and writing of the dna strand is from 5’ to 3’. When the dna strand is duplicated one strand is duplicated in the usual way and the other in inverse (because the strands are inverse directioned in the dna). The strand that is duplicated in the usual 5’ > 3’ is continuous and therefore leading. But the inverse cannot be duplicated in a continous line so its lagging and duplicated in fragments which are afterwards being connected with enzymes
Acceleration is change in velocity divided by time or
V/t so 60/3 = 20
Acceleration refers to the velocity (magnitude and direction) and speed refers only to the highest rate of speed something can obtain.
