How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

In order to maintain a stable internal environment, the cells of all living organisms must be able to

xenn [34]

Answer:<em> Living organisms must maintain a constant internal environment while living in a constantly changing external environment. </em>

Explanation: Maintaining the internal environment is important because the processes that keep the cell alive can only take place under certain conditions. There are different processes that occur in the body to maintain the constant internal environment such as diffusion, osmosis, homeostasis, active transport, passive transport, endocytosis, exocytosis, etc. Homeostasis helps to maintain an equilibrium of an internal environment.

"All of the following describe real experimental results. One does NOT support the predictions of Hamilton's rule. Which one?

liq [111]

Answer:

Option-C

Explanation:

Hamilton gave the mathematical expression for the altruistic behaviour or trait in a population which suggested that the alleles for altruistic behaviour will be favoured by the natural selection if BR-C > 0.

The mathematical expression for the altruistic trait is rb> c

where r - relatedness, b- the benefit to recipient and itself also and c-cost to an actor.

In the given question, all the cases meet the condition of Hamilton's rule except one which is the In- law bee-eaters which raise the young near to the nest as the parents who can raise the young ones are not benefited personally from the action of the young as the young one treat them as non-kin. This does not fulfill the condition of the Hamiltons rule.

Thus, Option-C is correct.

Heparin reacts to prevent the conversion of prothrombin to thrombin. Heparin:

Paha777 [63]

Answer:

The correct option is C) Heparin has its effects reversed with the administration of protamine sulfate.

Explanation:

Heparin is an anticoagulant, that is, it works by decreasing the ability of blood to clot, helping to prevent the formation of clots as well as stopping the subsequent extension of any existing clot. Through the neutralization of thrombin, it prevents the conversion of fibrinogen to fibrin, and thus, prevents the formation of a stable clot by inhibiting the fibrin stabilizing factor.

Protamine sulfate is a heparin antagonist, forming with it inactive complexes without anticoagulant effect, that is, the protamine, in the presence of heparin, which is acidic in nature, through the formation of stable salts, cancels the anticoagulant effect of both substances, neutralizing and reversing the anticoagulant action of heparin.
