Which of the following describes the correct stepwise assembly (in vitro) of the eukaryotic RNA polymerase II preinitiation comp

PilotLPTM [1.2K]

Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II

Explanation:

Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).

The liver forms glucose from noncarbohydrates. stores vitamin

Viefleur [7K]

The propositions are:
a. forms glucose from noncarbohydrates
b. does all of these
c. destroys damaged red blood cells
d. stores vitamin D
e. forms urea

The right answer is: B. does all of these

*The liver plays a role in the metabolism of carbohydrates:- gluconeogenesis (manufacture of a new glucose molecule from a non-carbohydrate molecule);- glycogenolysis (release of glucose from glycogen) under the effect of glucagon;- gluconeogenesis (storage of glucose in the form of glycogen) under the effect of insulin
*It stores fat-soluble vitamins (A, D, K and E) and glycogen.*It converts ammonia to urea (detoxification)*It recycles substances from the senescent red blood cells.

Which term describes organ systems that work together and maintain steady internal conditions when external conditions change?

Mashutka [201]

Answer:

I believe it is D.

Explanation:

Homeostasis refers to the relatively stable state inside the body of an animal. Animal organs and organ systems constantly adjust to internal and external changes in order to maintain this steady state

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

Luminous energy is trapped by chlorophyll in Photosystem II.
When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.
Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.
When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
The released energy is used to produce ATP molecules.
Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
