Pepsinogen is produced by __________ and is activated by __________
Ket [755]

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.

¿que organismo o institución en el Perú se encarga de estudiar el clima para realizar los perfiles climáticos?
kap26 [50]

El Ministerio de Medio Ambiente (MINAM) gestiona esto, lo gestiona a través del comité nacional sobre el clima.

El cambio climático en Perú es vulnerable y necesita altas adaptaciones. Hay una gran contribución al calentamiento global por el derretimiento de sus glaciares ubicados en los picos andinos.

La pesca y la agricultura en las regiones costeras de bajo nivel son propensas a la elevación de alta mar que puede destruir las infraestructuras económicas y disponibles presentes.

Esta institución de los gobiernos está haciendo un esfuerzo frenético para reducir esta vulnerabilidad, asegurando una reducción en la emisión de gases de efecto invernadero.

Además, el país está adoptando caminos con bajas emisiones de carbono en un intento por conservar la reserva forestal de carbono, con una mayor reducción de las emisiones de la combustión de combustible y otros sectores industriales.

Answer:

This is being managed by the ministry of environment(MINAM).It manages this through the national committee on climate.

The climate change in Peru is vulnerable and needs high adaptations.There is high contribution to global warming from the melting of its glaciers located on at the   Andean peaks.

Fishery and agriculture at low-levels coastal regions are prone to high sea rise which may destroy the  economic and available infrastructures present.

This institution of the governments is making frantic effort to reduces this vulnerability, by ensuring reduction in the green house gas emission.

Besides the country is embracing low carbon paths in an attempt to conserve the forest carbon reserve,with further reduction in emission from fuel combustion and other industrial sectors.
