The concentration of H ions inside the mitochondrial matrix

The concentration of H^+ ions inside the mitochondrial matrix is lower than it is in the cytosol or the mitochondrial intermembrane space. What would be the immediate effect of a membrane-permeable compound that carries and releases protons into the mitochondrial matrix? the electron-transport chain inhibition ATP synthesis import of ADP into the matrix inhibition of the citric acid cycle the intermediates of the citric acid cycle are constantly being depleted because they are used to produce many of the amino acids needed to make proteins. The enzyme pyruvate carboxylase converts pyruvate to oxaloacetate to replenish these intermediates. Bacteria, but not animal cells, have additional enzymes that can carry out the reaction acetyl CoA + oxaloacetate + succinate. Which of the following compounds will not support the growth of animal cells when used as the major source of carbon in food, but will support the growth of no photosynthetic bacteria? Select the best option to fill in the blanks of the following statement: Fermentation is a/a _process that converts__ into carbon dioxide and anaerobic, pyruvate, ethanol lactate, ethanol glyceraldehyde 3-phosphate, ethanol prokaryotic, lactate, propanol

Solution

Answer:

11). C). Increased import of ADP into the matrix.

Protons are pumped into mitochondria matrix through ATPsynthase. While protons moving through ATP synthase, energy is released. The energy is utilized to combine ADP with inorganic phosphate (ip). So that import of ADP into the matrix will be increased.

12). C). Fatty acids

13). B). Anaerobic, pyruvate, ethanol.

Glucos-------------2 pyruvate-------------2ethanol + CO2
