Two intracellular molecules, x and y, are both normally synthesized at a constant rate of 1000 molecules per second per cell. molecule x is broken down slowly – each molecule of x survives on average for 100 seconds. molecule y is broken down 10 times faster – each molecule of y survives on average for 10 seconds. a) calculate how many molecules of x and y the cell contains at any time? and what if the rates of synthesis of both x and y are suddenly increased tenfold to 10,000 molecules per second per cell in response to a signaling cascade, without any changes in respective degradation rates, how many molecules of x and y will there be after one second?

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

is it multiple choice?

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
