Answer:
Phosphate from the dephosphorylation of the liver isozyme is used to generate ATP and provide energy for movement.
Glycolysis is inhibited in the liver, but not muscle, when blood sugar is low.
Explanation:
cAMP-dependent protein kinase (PKA) is a group of enzymes that function in the presence or absence of cyclic AMP (cAMP). They depend on the release of this cAMp to initiate response such as regulation of glucagon, sugar and even lipid metabolism in the body.
Phosphorylation of the cAMP-dependent kinase leads to the inactivation of phosphorylase in the liver thereby inhibiting glycolysis which is the break down of glucose molecules to form energy (ATP) and stimulates glycogenesis which is the break down of glycogen in the liver to form energy. When the blood glucose level reduces, elevated levels of glucagon leads to the increase in the level of cAMP which causes phosphorylation and inactivation of the liver enzyme thus glycolysis and stimulation of gluconeogenesis.
In the muscle cells, the release of cAMP instead causes the stimulation of glycogenolysis by phosphorylating glycogen through phosphorylase kinase and glycolysis and inhibition of glycogenesis by inhibiting glycogen synthase.
cAMP- dependent protein kinase inactivation of the liver isozyme and not the muscle isozyme is to sure rapid supply of energy to the muscle cells for movement and also from the liver through the breakdown of glycogen stored in it. The other two options do not occur by the action of cAMP-dependent protein kinase .

<u>1. interaction between atmosphere and biosphere.</u>
An example of this interaction would be the way in which plants give out carbon dioxide and absorb oxygen from the air. Plants are able to do so directly from the air through their stomata.
<u>2. interaction between atmosphere and geosphere.</u>
The atmosphere provides the geosphere with the energy necessary for the breakdown of rocks and erosion. The geosphere reflects the energy of the sun back to the atmosphere.
<u>3. interaction between hydrosphere and atmosphere.</u>
The water cycle is a good example of this interaction, as well as the weather phenomena that come from it (rain, snow, etc.)
<u>4. interaction between hydrosphere and geosphere.</u>
An example of such an interaction would be the erosion that is caused by water in rivers and waterfalls.
Answer:
No sé si esto ayuda, pero espero que sí. Un promedio de 137 especies de formas de vida se extinguen todos los días en las selvas tropicales del mundo. Las fuerzas de destrucción como la tala y la ganadería han contribuido a la pérdida de millones de acres de selva tropical. Los animales pueden morir a medida que se destruye su hábitat y enfrentar la competencia por alimentos, agua y otros recursos al verse obligados a migrar a regiones vecinas. Por estas razones, la destrucción del hábitat es una de las razones clave por las que los animales se ponen en peligro o se extinguen. Las presiones más comunes que causan la deforestación y la degradación forestal severa son la agricultura, el manejo forestal insostenible, la minería, los proyectos de infraestructura y el aumento de la incidencia e intensidad de los incendios. Los orangutanes, tigres, elefantes, rinocerontes y muchas otras especies están cada vez más aislados y sus fuentes de alimento y refugio están en declive. El conflicto entre humanos y vida silvestre también aumenta porque sin un hábitat natural suficiente, estas especies entran en contacto con los humanos y, a menudo, son asesinadas o capturadas. Más recientemente, los científicos de la Convención de las Naciones Unidas sobre la Diversidad Biológica concluyeron que: "Cada día, se pierden hasta 150 especies". Eso podría ser hasta un 10 por ciento por década.
Espero que esto te ayude, que tengas un gran día / noche y mantente a salvo.
