In liver cells, glycogen phosphorylase acts in which of the three stages of the signaling pathway associated with an epinephrine
goldenfox [79]

Answer:

The second stage.

Explanation:

Epinephrine is a hormone that is released by the glands over the kidneys that initiate a fight-or-flight response sequence in the body which starts with the segregation of the hormone and ends with the release of glucose into the bloodstream by the liver to provide energy required for the situation by the body.

The liver cells acts in the second stage of the epinephrine initiated signal with glycogen phosphorylase enzyme. The released epinephrine activates an enzyme called phosphorylase kinase and that in turn activates glycogen phosphorylase. Lastly glycogen phosphorylase reacts to epinephrine and releases another enzyme to remove the phospate from the glycogen phosphorylase group to form glucose that will be released into the bloodstream for energy.

I hope this answer helps.

How does photosynthesis vary in different seasons? Different environments?
slega [8]

Plants found in cold environments have a higher amount of photosynthesis at low temperatures. Plants in warm environments, have a higher photosynthesis in high temperatures.

Photosynthesis is the process by which plants make their food from sunlight . This process is mostly dependent on sunlight so it varies from temperature and seasons. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.

Photosynthesis is generally higher during early summer and decline by autumn season . Temperature also plays an important role in photosynthesis as temperature increases the number of collisions increases, therefore the rate of photosynthesis also increases.
