Answer:
ATP synthase will hydrolyze ATP and pump protons into the intermembrane space.
Explanation:
Under normal conditions, the intermembrane space of mitochondria has higher proton ion concentration than the matrix. The inner mitochondrial membrane is impermeable to protons. The concentration gradient drives pass movement of protons through proton channels and the energy is used to drive the synthesis of ATP. The synthesized ATP molecules are released in the matrix.
If the matrix has higher ATP concentration and the proton concentration in intermembrane space is low, ATP synthase would use the energy of hydrolysis of ATP to pump protons from matrix towards intermembrane space. These conditions would not support ATP synthesis.
Answer:
B
Explanation:
Great variations in temperature and pH from the optimum that an enzyme needs can affect its function. pH affects ionization of the functional groups of amino acids. The interaction of charges of these amino groups helps in stabilizing loops such as those of beta sheets and alpha helices and give the protein its an appropriate shape to function.
Temperatures, on the other hand, while it does not change the ionization of the functional side groups of amino acids, it breaks these bonds of the interactions by giving the molecules enough energy to break free from these bonds hence denaturing the protein.
Carl woeses's work separated prokaryotes into two groups, originally called Eubacteria and ARCHEA.
Answer:
Cellular respiration
Explanation:
Cellular respiration is the process through which organic compounds are broken down enzymatically to release energy in form of ATP in the cell. Cellular respiration occurs in the mitochondria and cytoplasm.
Mitochondria contain enzymes that catalyze and control reactions of respiration. The inner membrane is folded into cristae to create large surface area for attachment of enzymes. The end products of cellular respiration are carbon dioxide, water and energy.
