Blood lactate is a biochemical by-product that is produced during high-intensity exercisedue to insufficient oxygen intake. Commercially available drinks advertised as oxygen sup-plements claim to increase exercise performance and decrease the postexercise recoveryperiod by decreasing the accumulation and accelerating the removal of blood lactate.To test this claim, researchers conducted a controlled experiment to compare the concen-tration of blood lactate during exercise and during recovery between two participantgroups, one that ingested oxygen-supplemented water and another that ingested regularwater.(blood lactate (mmol/liter)CABstartсExerciseDmiddle-o-oxygen-supplemented water--regular waterfinishblood lactate (millimole/liter)bNThe mean blood lactate concentration during exercise (left) and recovery (right)Which of the following best describes the results of the experiment?Recovery3 6 9 12 15 18 21 24 27 30time (mins)--oxygen-supplemented waterregular waterOxygen-supplemented water has a more significant effect on the removal of blood lac-tate during the early recovery period than in the later recovery period.Oxygen-supplemented water has a less significant effect on the accumulation of bloodlactate than its removal.Oxygen-supplemented water has a more significant effect on the accumulation of bloodlactate than its removal.Oxygen-supplemented water has a more significant effect on the accumulation of bloodlactate in the early exercise period than in the later exercise period.

A plant breeder has developed a new frost-resistant variety of tomato that contains higher levels of unsaturated fatty acids in membrane lipids than those found in standard tomato varieties. However, when temperatures climb above 95°F, this frost-resistant variety dies, whereas the standard variety continues to grow. Provide a likely explanation of the biochemical basis of increased tolerance to cold and increased susceptibility to heat of this new tomato variety.
It is not an easy matter to assign particular func-tions to specific components of the basal lamina, sincethe overall structure is a complicated composite materialwith both mechanical and signaling properties. Nidogen,for example, cross-links two central components of thebasal lamina by binding to the laminin γ-1 chain and totype IV collagen. Given such a key role, it was surprisingthat mice with a homozygous knockout of the gene fornidogen-1 were entirely healthy, with no abnormal phe-notype. Similarly, mice homozygous for a knockout of thegene for nidogen-2 also appeared completely normal. Bycontrast, mice that were homozygous for a defined muta-tion in the gene for laminin γ-1, which eliminated just thebinding site for nidogen, died at birth with severe defectsin lung and kidney formation. The mutant portion of thelaminin γ-1 chain is thought to have no other functionthan to bind nidogen, and does not affect laminin struc-ture or its ability to assemble into the basal lamina.…

In studies trying to understand the regulation of hormone-sensitive adenylatecyclase, it was discovered that non-hydrolyzable GTP analogs and cholera toxin (that inhibits theGTPase activity of Gs ) were able to activate the enzyme in a sustained (irreversible) profile, thereforeindicating that GTP hydrolysis represents a deactivation (turn-off) regulatory step.a) Will these analogs or toxin have any effect on adenylate cyclase activity in the absenceof any added hormone?b) If you add an factor that increases the rate of GTPase hydrolysis of the Gs protein, willthis activate or inhibit the observed downstream effect upon addition of the hormone (this is in theabsence of GTP analogs or toxin). Explain your answer.
