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.
The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". Triple sugar iron test (TSI), Urease Test and Malonate Test are also included in this test.
For each of the tests, different reagents are added to the species are inoculated and tested.
For Salmonella sp. the IMViC Test result is:
Indole - negative
Methyl red - Positive
Voges-Proskauer - negative
Citrate - positive
It's some change in the conditions around the organism, which the organism can detect and respond to. A change in temperature, more light, or something physically poking the organism are examples.
