Answer:

Explanation:

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

<h2><em>what is an atomic mass of an atom referring to?</em></h2>

  • <em>Lr. The atomic mass of an element is the average mass of t<u>he atoms of an element measured in atomic mass unit </u>(amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.</em>

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
