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:
Description
An electron cloud is the region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital. It is defined mathematically, describing a region with a high probability of containing electrons.
Grasshopper and cricket are two organisms in the food web would MOST LIKELY be affected by a decrease in producers, or the plants, at the bottom base of the food web.
D) grasshopper and cricket
<u>Explanation:</u>
A food web comprises of many food chains. An evolved way of life just follows only one way as creatures discover food. It is an enormous number of plants and creatures things. A food web shows a wide range of ways plants and creatures are associated with one another for their prey.
Though Grasshopper and cricket are two living beings in the nourishment web that would be generally influenced by a diminishing in makers, or the plants, at the base of the nourishment web.
Like every living life form, crickets and grasshoppers assume a significant job in keeping up the equalization of the biological system. They breakdown plant material, restoring soil minerals. They are also an important source of food for other animals.
The answer is A: yes
Hope this helps
Answer:
1. nucleus- formation of ribosomal subunit
2. cytoplasm- attachment of amino acid to tRNA.
3. free ribosomes- cytoplasmic protein synthesis
4. chromatin- transcription and RNA processing
5. ribosomes: secretory protein synthesis
Explanation:
The nucleolus is the place in the nucleus where the ribosomal proteins enter and combine to form two ribosomal subunits. Therefore ribosomes are formed in the nucleus.
In the cytoplasm, free ribosomes are present which synthesize cytoplasmic protein and in the cytoplasm, amino acids attach to tRNA molecules and make aminoacyl tRNA which helps in making protein during translation.
Chromatin which is less condensed are transcribed in the nucleus into mRNA and this mRNA goes through RNA processing for mature mRNA.
Ribosomes are also attached with RER which is responsible for the production of secretory proteins that moves out of the cell.
