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
+ 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
+ 1 × 96500 × 0.160
ΔGt = 5517.25
+15440
ΔGt = 5517.25
+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
Answer:
Ribsosmes (sry, can't spell it correctly, i'm trying to multi task...)
Explanation:
Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located. (hope this helps! :) ))
Answer:
16y²
Explanation:
The exponent outside the parentheses will be distributed to both terms
(4²)(y²)
= 16y²
Answer:
This type of secretion is known as Holocrine. Whereby the entire cell and content is released
<h3><u>Answer;</u></h3>
Gap junctions
<h3><u>Explanation;</u></h3>
- Gap junctions allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.
- <em><u>Action potentials generated by the autorhythmic cells spread waves of depolarization to contractile cells through gap junctions. If the depolarization causes the contractile cells to reach threshold, they will in turn generate an action potential.</u></em>
