Dinitrophenol increases the permeability of the lipid bilayer of the inner mitochondrial membrane to protons. Assuming that all

other processes are unaffected by this chemical, what effect do you think it will have on the generation of ATP in the mitochondrion?A It will have no effect because protons will still flow down through ATP synthase to generate ATP. B. It will increase ATP production because more protong will be able flow down through ATP synthase. C.It will decrease ATP production because fewer protons will be able flow down through ATP synthase. D.It will have no effect because because the ATP production from the citric acid will be able to make up the E. It will increase ATP production because more protons will be able to enter the intermembrane space for difference to activate ATP synthas

Answer:

The correct answer is : C .It will decrease ATP production because fewer protons will be able flow down through ATP synthase.

Explanation:

  • Oxidative Phosphorylation is a process which involves two steps:  
  1. Transport of electrons from the reduced compounds like NADH (Nicotinamide adenine dinucleotide hydrogen) and FADH₂ (Flavin adenine dinucleotide dihydrogen) through the electron transport complexes, located in the inner mitochondrial membrane, to oxygen for the generation of water molecules.
  2. Synthesis of ATP or adenosine triphosphate from ADP or adenosine diphosphate and inorganic phosphate by an enzyme called ATP synthase which is located in the inner mitochondrial membrane. This enzyme harnesses energy by carrying protons from the inter-membrane space into the mitochondrial matrix and in the process produces ATP.
  • Oxidative phosphorylation takes place in the mitochondria, especially involving the inter membrane space, inner membrane and mitochondrial matrix
  • During the transport of electrons through the protein complexes (I, II, III, IV) of the electron transport chain a proton gradient is generated across the inner mitochondrial membrane.
  • The proton gradient is such that the concentration of protons is more in the inter-membrane space and less in the matrix of the mitochondria.
  • This proton gradient provides the energy to the ATP synthase for the synthesis of ATP.
  • Dinitrophenol is responsible for making the inner mitochondrial membrane permeable to protons. As a result protons can directly diffuse through the inner mitochondrial membrane from the inter-membrane space into the mitochondrial matrix equalising the concentration of protons across the inner mitochondrial membrane. This causes distortion in the proton gradient.  Hence, protons are no longer available for the ATP synthase to operate and synthesise ATP.

A mitochondrion cannot produce new molecules. which structure is most likely not functioning properly?
snow_lady [41]
<span>It is likely that the hydrogen pump is not functioning properly. The hydrogen pump sends hydrogen ions through membranes. It is crucial in the production of ATP, or energy, which is the main product that the mitochondria makes. The functioning of the mitochondria is essential to the functioning of the cell.</span>

For mitochondria where an uncoupler for oxidative phosphorylation is present, which statement is TRUE?
olga nikolaevna [1]

Answer:

The correct answer is statement d.

Explanation:

In oxidative phosphorylation that takes place in mitochondria, the uncouplers prevent the coupling in between the phosphorylation reactions and electron transport, and therefore, prevent the synthesis of ATP without influencing the ATP synthase and respiratory chain.  

The uncoupler always exhibits its influence on the synthesis of ATP. The 2,4-dinitrophenol functions as an uncoupler at the time of oxidative phosphorylation. The NADPH and FAD functions as an electron carrier.

Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the show
Aleonysh [2.5K]

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <vector>//defining header file

using namespace std;

void PrintVectors(vector<int> numsList)//defining a method PrintVectors that accept an array

{

   int j;//defining integer variable

   for (j = 0; j < numsList.size(); ++j)//defining for loop for print array value  

   {

       cout << numsList.at(j) << " ";//print array

   }

   cout << endl;

}

int main()//defining main method  

{

   vector<int> numsList;//defining array numsList

   numsList.push_back(101);//use push_back method to insert value in array

   numsList.push_back(200);//use push_back method to insert value in array

   numsList.push_back(103);//use push_back method to insert value in array

   numsList.erase(numsList.begin()+1);//use erase method to remove value from array

   numsList.insert(numsList.begin(), 100);//use insert method to add value in array

   numsList.insert(numsList.begin()+2, 102);//use insert method to add value in array

   PrintVectors(numsList);//use PrintVectors method print array value

   return 0;

}

Output:

100 101 102 103  

Explanation:

In the above-given code, inside the main method an integer array "numList" is defined, that use insert method to insert value and use the erase method to remove value from the array and at the last "PrintVectors" method is called that accepts a "numList" in its parameter. In the "PrintVectors" method, a for loop is declared, that prints the array values.
