Consider a cell in which Cl- distributes passively across the membrane according to the membrane potential. The resting membrane

UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60 mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60 mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K'] = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM

A ribozyme is a catalytic protein that assists in the processing of trna. a. True b. False

FinnZ [79.3K]

Answer:
The correct option is a (True).

Explanation:

Carl Woese, Francis Crick, and Leslie Orgel were the first to suggest that RNA could act as a catalyst in 1967. This idea was based upon the discovery that RNA can form complex secondary structures. Nick et al. (2000) have reported that ribozyme play a key role in catalyzing tRNA amino-acylation.
