Hagfish (eptatretus cirrhauts) are a jawless marine vertebrate that are isotonic with their environment and are considered to be

Elenna [48]

I think the Hagfish habitat is limited by the salinity of the environment. Hagfish are the most pleisiomorphic extant craniates, and based on the similarity of ionic concentrations between their internal milieu and sea water, they have long referred as a model for osmo- and ionoconformation.

What is the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells at night w

lions [1.4K]

Answer:

C. +23.1 kJ/mol

Explanation:

the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:

ΔGt = RTIn $\frac{C_{2} }{C_1}$ + ZFΔV

let's list the values of the data we are being given in the question to make it easier when solving it.

Z= 1

F= 96500C (faraday's constant)

ΔV= 160mV = 0.160V

R= 8.314( constant)

T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)

∴ T= 288.15K

Putting it all together in the formula, we have:

ΔGt = 8.314 × 288.15 × 2.303 log $\frac{C_{2} }{C_1}$ + 1 × 96500 × 0.160

ΔGt = 5517.25 $[ -(log(H^{+}_{out} ) + log(H^{+}_{in} )_{in}$ +15440

ΔGt = 5517.25 $(pH_{out} - pH_{in}$ +15440

Given that the pH differential gradient across the membrane is 1.4pH units. It implies that;

ΔGt = 5517.25 × 1.4 + 15440

= 7724.15 +15440

= 23164.15 Joules/moles

= +23.1 KJ/mole
