about ATP synthase [Cellular Respiration] Which of the following interactions provides the mechanical energy needed to promote ATP production? Non-polar interaction Salt bridge formation Polar interaction : Attractive Polar interaction : Repulsive
Choose any/all that apply to the proton-motive force and ATP synthesis. The active pumping of protons through ATP synthase against their concentration gradient provides the energy needed for ATP synthesis. Rotation of the y subunit creates conformational changes in the active sites of ATP synthase that drive the release of ATP from the enzyme. Each 3 subunit of ATP synthase has a distinct amino acid sequence that accounts for the three different active sites present in the enzyme. The ATP molecules produced from the pair of electrons provided by NADH have greater potential energy than the ATP molecules produced from the pair of electrons provided by FADH₂. Inhibition of either ATP synthase or ATP translocase will stop flux through the electron- transport chain.
Which of the following statements about nucleotides are true? Indicate all that are true. O CAMP and CGMP are second messengers As AMP is produced from ATP in cells, it reacts with remaining ATP, allowing ADP to accumulate as a hunger signal O The ratio of [ATP/[ADP] is kept fairly constant in living, non-starved cells O The KM for a typical ATP dependent enzyme is around the typical concentration of ATP in a cell O A bacterial cell (exclusively) fermenting glucose to form lactic acid will have a net yield of 2 ATPS for each lactic acid molecule produced
In the rete mirabile serving the red swimming muscles oftunas, some key enzymes of catabolism show gradients ofconcentration: They are more concentrated at the cold end of therete, and less concentrated at the warm end. These variationsparallel variations that are often seen in the thermal acclimationof poikilotherms, when enzyme concentrations rise duringacclimation to cold and fall during acclimation to heat. Whatdo you think could be some of the reasons for these spatial andtemporal variations in enzyme concentration? Why not havethe highest observed enzyme concentrations everywhere at alltimes?
The reaction pathway labeled (A) below represents a substrate (protein) and a specific coenzyme (ATP). Reactions such as that found in (A) are catalyzed by enzymes called ATP (P ADP A Protein Protein
Different enzymes that catalyse the same reaction are called O A. isoenzymes O B. holoenzymes O C. cofactors O D. coenzymes O E. agonists Which statement concerning the glycolytic and gluconeogenic pathways is correct? O A. Both are catabolic. O B. Both are anabolic. O C. Gluconeogenesis is catabolic while glycolysis is anabolic. O D. Gluconeogenesis is anabolic while glycolysis is catabolic. O E. Gluconeogenesis occurs in brain and glycolysis occurs in muscle. In lactic acid fermentation, which substance is oxidized and which is oxidized? O A. Lactate is reduced and NAD* is oxidized. OB. Lactate is reduced and pyruvate is oxidized. OC. Pyruvate is reduced and NADH is oxidized. O D. NADH is reduced and pyruvate is oxidized. O E. Lactate is oxidized and NADH is reduced.

V-class proton pumps run backward relative to the F-class ATP synthase. Consider the cartoon, which shows the conformations of the beta-subunits and ATPIADP + Pj of the F-class synthase. Which of the following associations between the conformation of the beta subunit and ATP/ADP + P¡ is correct for V- Binding Change Mechanism loose binding ADP+P ATP ATP class pumps? C repeat ADP + P, ADP АТР tight binding АТР +P оpen АТР O The open conformation releases ATP. Hydrolysis of ATP to ADP + P¡ drives the change from tight to loose. O Binding of ADP + P¡ drives change from open to loose. Hydrolysis of ATP to ADP + Pj drives the change from open to loose.
In vision, vitamin A serves as a cofactor for key enzymatic reactions needed for vision O is covalently attached to an eye protein to make a photon sensor is a molecule that changes structure in response to light, and then interacts with opsin to send a visual signal O provides critical anti oxidant functions to the retina
(cell biology/human physiology) 1) Is it true that AMP and ADP levels are similarlyly indicators of energy status (as shown by ATP concentration) 2) Explain the change of peaks from I to V in the sequence of events from A to D?
