Under normal cellular conditions, the FoF1 complex of the inner mitochondrial membrane functions to create new ATP. Under non-physiologic experimental conditions, isolated FoF1 complex can be driven in reverse as long as [ATP] is high. Which of the following would be true under such conditions? A. The FoF1 complex would be operating as an ATPase rather than an ATP synthase.
B. The FoF1 complex would be driving net H+ movement from the matrix side to the IMS (intermembrane space) side
C. The FoF1 complex would create more ATP, per unit time, than it does under physiological conditions
D. As the experiment continues, we would expect to see higher & higher concentrations of ADP.
E. The FoF1 complex would effectively be operating as a proton pump.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

What is the similarities and differences between bacteria and eukaryote?

According to the cell theory, which describes cells? a. all organisms are composed of multiple cells. b. all cells have the same structure and function. c. cells are found in everything on earth. d. living organisms are not created spontaneously
