Which of the following allosterically activates mammalian isocitrate dehydrogenase?a. ADPb. NADHc. ATPd. MalateCitrate
Bogdan [553]

Answer:

a. ADP

Explanation:

Isocitrate dehydrogenase is an enzyme in citric acid cycle that occurs in mitochondrial matrix.

It catalyzes conversion of the isocitrate to the alpha-ketoglutarate and Carbon dioxide which occurs in a two step process.

<u>IDH is regulated allosterically by the ADP positively in the mammals and inhibited by ATP, NADH.</u>  

The enzyme, IDH will not catalyze the reaction unless there are low levels of ADP.

A sample of gas is held at 100oc at a volume of 20 L.if the volume is increased to 40 L what is the new temperature of the gas i
ElenaW [278]

Answer:

470 °C  

Explanation:

This looks like a case where we can use Charles’ Law:  

\dfrac{V_{1}}{T_{1}} =\dfrac{V_{2}}{T_{2}}

Data:

V₁ = 20 L; T₁ = 100 °C

V₂ = 40 L; T₂ = ?  

Calculations:

(a) Convert the temperature to kelvins

T₁ = (100 + 273.15) K = 373.15 K

(b) Calculate the new temperature

\begin{array}{rcl}\dfrac{V_{1}}{T_{1}}& =&\dfrac{V_{2}}{T_{2}}\\\\ \dfrac{\text{20 L}}{\text{373.15 K}} &=&\dfrac{\text{40 L}}{T_{2}}\\\\{\text{15 000 K}} & = & 20T_{2}\\T_{2} & = &\dfrac{\text{15 000 K}}{20 }\\\\T_{2} & = & \textbf{750 K}\\\end{array}

Note: The answer can have only two significant figures because that is all you gave for the volumes.

(c) Convert the temperature to Celsius

T₂ = (750 – 273.15) °C = 470 °C

What is the name of this molecule?
Neko [114]
The triple bond is in the first place, not the 3rd because we have to choose the smallest possible number. That means the name will be: ‘but-1-yne’ or ‘1-butyne’
