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

laila [671]

When jacob greeted stephanie at the beach, he reached out with the volar surface of his hand to grasp the palmar surface of her hand for a handshake. As the anterior aspect of their bodies faced each other, jacob noticed that the hair located on the most superior part of Stephanie's head appeared to be a different color than he remembered.

The volar surface is associated with the palm or the sole, the palmer surface is the palm or gripping part of the hand, the anterior aspect of the body is the front part of the body while the most superior part of the human body is the head.

After an intense workout, christa's weight was down 3 pounds. to rehydrate adequately, christa should drink 6 to 9 cups of water over the next hour or two.


Explanation;

It is very important to rehydrate after intense exercise as water helps the body in that;

-Water regulates your body temperature and lubricates your joints.

-It helps transport nutrients to give you energy and keep you healthy.

-Additionally, drinking plenty of water can help flush out toxins from your body and prevent dehydration, which can make muscle soreness even more painful

Andrej [43]
Independent of whether an organism is an endotherm or ectoderm, the least reliable indicator of an animal's metabolic rate is the amount of water consumed in one day.  The metabolic rate is the speed at which chemical reactions take place in the body and varies because of several factors including age, gender and inherited factors.  It is also affected by the proportion of muscle to fat in the body , amount of exercise and other physical activity.
