Which statement is FALSE about ATP? (A) Its concentration is maintained in part by adenylate kinase.(B) The concentration of ATP
DENIUS [597]

Answer:

(B) The concentration of ATP in cells is generally much lower than that of AMP.

Explanation:

AMP is 5’-adenylic acid or adenosine monophosphate. It has only one phosphate group attached to the sugar as compared to three phosphate groups of ATP. In general, cells have a much lower concentration of AMP than ATP. ATP is found in much higher concentration in cells than the AMP since ATP serves as energy currency for the cells while AMP is involved in relatively few metabolic pathways.

A cloud directly above you is about 10° across. From the weather report, you know that the cloud is at an altitude of 2200 m. Ho
Vikentia [17]

The width of the cloud is : 384 m

<u>Given data :</u>

Cloud altitude = 2200 m

Temperature = 10°

<h3></h3><h3>Determine how wide the cloud is </h3>

applying the equation below

I = d(\frac{\alpha }{57.3})

where : I = linear size , d = 2200 m ,  \alpha  = 10^{o}

therefore :

I = 2200 ( 10 / 57.3 )

 = 383.94 m

 ≈ 384 m

Hence we can conclude that the width of the cloud is : 384 m
