(a) A cell where PKB is always active has a mutation that results in the permanent activation of GSK3. Based on the information in Figure 2, predict the effect of this mutation on the activity of glycogen synthase. Justify your prediction.

Answers

Answer 1

Answer:

a. Normally, PK2 activates PK1. We are told that PK1 and PK2 normally work sequentially in an intracellular signaling pathway. If PK1 is permanently activated, a response is seen independently of whether or not PK2 is present. If PK1 activated PK2, no response should be seen if PK1 were activated in the absence of PK2.

GSK-3 is an unusual protein kinase in that it displays high, “constitutive” activity in unstimulated cells and is rapidly inactivated upon a variety of cellular stimulations. The most thoroughly documented pathway for the inactivation of GSK-3 is in response to insulin and is mediated by protein kinase B (PKB, also termed Akt), which lies upstream of GSK-3 [8].

Answer 2

A cell wherein the PKB seems to be constantly active does indeed have a disorder that makes GSK3 to be permanently activated. Kinases, for example, control glycogen synthase as well as glucose acid phosphatase.

GSK3, as well as glycogen synthase kinases 3, is however one enzyme that is controlled through PKB phosphorylase kinases.Throughout one cell, PKB seems to be constantly in motion, culminating in GSK3 regulation, which would, in turn, be responsible for glycogen synthase activities only through the signaling cascade.

Thus the response above is correct.

a. The wavelength is short
b. The wavelength is long
c. Must be a mechanical wave

Answer:

Evolution occurs about 6 million years ago.

Explanation:

The mammoth evolved from the common ancestor because evolution occurs about 6 million years ago. The modern elephants and woolly mammoths share a common ancestor and they are split into two separate species about 6 million years ago due to change in genetics as well as environment that leads to the evolution in the elephants.

Simplify the combined equation for photosynthesis by crossing out compounds that are both products and reactants. How does this equation compare to the general equation for photosynthesis (CO

Answers

Answer:

The simplified equation is as follows:

CO2 + H20 + light energy ---> glucose + O2

Comparing this simplified equation with the general equation of photosynthesis (CO2+ H2O + light energy → [CH2O] + O2), it can be concluded that the process of photosynthesis is a two-stage process, and that a combination of the reactions of the two processes gives the products of photosynthesis

Note: The question is incomplete. The complete question is given below:

Simplify the combined equation for photosynthesis by crossing out compounds that are both products and reactants. How does this equation compare to the general equation for photosynthesis (CO2+ H2O + light energy → [CH2O] + O2)?

Explanation:

Photosynthesis -the process by which plants use the energy of the sunlight to produce sugars- occurs in two stages: the light-dependent stage and the light-independent stage.

The light reactions occuring in the thylakoid membranes use the energy of sunlight to split water producing electrons which are transferred to NADP+ to produce NADPH and ATP from ADP and Pi

Light energy + H20  + ADP + Pi + NADP+ ---> 02 + NADPH + ATP

In the light-independent reactions occuring in the stroma, energy from ATP and NADPH in addition with carbon dioxide in the atmosphere is used  to produce glucose

NADPH + ATP + CO2 ---> glucose + ADP + NADP+

The combined equation of the two reactions is given below:

CO2 + H20 + light energy + ADP + ATP + NADPH + NADP+ + ---> glucose + 02 + ATP + NADPH +ADP + NADP+

The simplified equation is as follows:

CO2 + H20 + light energy ---> glucose + O2

Comparing this simplified equation with the general equation of photosynthesis (CO2+ H2O + light energy → [CH2O] + O2), it can be concluded that the process of photosynthesis is a two-stage process, and that a combination of the reactions of the two processes gives the products of photosynthesis

While studying environmental samples collected from the ground cover of the Amazon rainforest, you isolate a new microorganism. You note that it is single-celled, lacks a nucleus, and is found only in areas of the rainforest that remain humid year-round. Based on this information, how would you best describe this organism

Answers

Answer:

The organism is a prokaryote from the domain Archaea since it lacks organelles and lives in what can be considered an extreme environment.

Explanation:

The organism is single-celled and lacks a nucleus. Prokaryotic organisms generally lack nuclei and other membrane-bound organelles such as mitochondrion and chloroplast. Hence, both attributes are characteristic of a typical prokaryote although being unicellular is not exclusive only to prokaryotes.

Prokaryotes can be bacteria of Archaea. The organism, in this case, also lives in an area that is humid all year round. Such an area can be considered to be an extreme environment. Living in extreme environments is a characteristic that is peculiar to Archaea only.

Organisms in the Archaea domain are generally prokaryotic, unicellular, and live in extreme habitats such as hydrothermal vents, marshes, hot springs, etc.
