Earl Sutherland won the Nobel prize for discovering how epinephrine stimulates the breakdown of glycogen, a molecule that belong

s to the carbohydrate family of macromolecules. Glycogen is abundant in liver and in muscle cells and is stored in glycogen granules. When epinephrine interacts with the liver cells it triggers a signal transduction cascade that leads to activation of glycogen phosphorylase and production of glucose-1-phosphate molecules. The glucose-1-phosphate molecules are then used for glycolysis to produce energy in the liver cell. To decipher the signal transduction pathway that triggers the breakdown of glycogen Sutherland and his colleagues used a test tube, the enzyme glycogen phosphorylase, epinephrine and glycogen. In this experiment he observed that no glucose-1-phosphate was formed. Why do you think this happened?

Answer:

There was no receptor for epinephrine to associate with and invigorate the sign transduction course that prompts the actuation of the compound  

By and large, Earl Sutherland helped in translating and discovering the breakdown of the glycogen into glucose-1-phosphate in nearness of glycogen phosphorylase and this sign course pathway is activated by the epinephrine. The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.

bagirrra123 [75]

Answer:

1, 4, 5 are true. 2, 6, 7, 9 are not true. 3 and 8 are not known.

Explanation:

According to the information we have gathered from the vehicles sent to Mars and the data they collected and analyzed, "Minerals of types known to form in liquid water" on Mars. There is "abundant water ice" and also "dried-up river beds".These statements actually exist.

"Surface pools of liquid water" does not exist on Mars. "A network of straight-line canals", "cities built by an ancient civilization" and "frequent rainfall and snowfall" also do not exist on Mars according to the data.

We do not have any information to prove the existense of "underground pockets of liquid" and "microscopic life" but they are possibilities.

I hope this answer helps.

Which two statements are true regarding an energy pyramid
ivolga24 [154]
This is an ecosystem energy pyramid that illustrates how much energy is found at each trophic level of a food chain. Select all the statements about this pyramid that are TRUE.

Approximately 90% of energy from one trophic level is transferred to the next trophic level.

Looking at the total amount of energy in an ecosystem, most energy can be found in the primary consumers.

This energy pyramid explains why there are few tertiary consumers in most ecosystems.

Looking at the total amount of energy in an ecosystem, most energy can be found in the producers.

Investigator A has biological specimens that are coded and linked to identifiers of the source individuals. Investigator A provi
ladessa [460]

Answer:

The correct answer is option C.

Explanation:

Human subject research is an investigation or research that include human as the subject. In other words, An Investigator conducts clinical research on humans getting data through interaction and intervention of individuals.

investigator A has investigated biological specimens. These specimens are coded and linked to the identifiers. Investigator B's research using biospecimens human subject is not according to the human subject research in the federal regulations as investigator B did not get the individual identifiers.

Thus, the correct answer is option C.

A pink unicorn is crossed with a blue unicorn and all of the offspring are lilac, caused by the presence of both pink and blue h
siniylev [52]

Answer:

The correct answer is codominant.

Explanation:

A phenomenon in which two heterozygous alleles get expressed completely in the offspring produced is termed as codominance, and the trait produced is termed as a codominant trait. In codominance, both the alleles show their presence, that is, none of them is considered dominant, and like incomplete dominance, the alleles do not get mixed up.  

For example, in the given case, the crossing between a pink unicorn and a blue unicorn produces an offspring, which is demonstrating both pink and blue color fur. This shows that the phenomenon of codominance is taking place and the produced trait is an illustration of codominant trait, as the produced offspring is having both pink and blue color hair.
