Why do we need to eat

A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy. (So we don’t die:))

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

What does "DNA" stand for? Why is genetic material named that?

Tresset [83]

“DNA” stands for: Deoxyribonucleic Acid

The researchers used different radioactive elements to label the DNA and proteins in viruses. This allowed them to identify which molecule the viruses inserted into bacteria. DNA was the molecule they identified. This confirmed that DNA is the genetic material.
