HELP...............HELPHI FRIENDS HELP ME OUT IN SOLVING THE FOLLWING QUESTIONS ASAP:
1.
THE BILOLOGICALLY ACTIVE CONFORMATION OF TRIMERIC G-proteins REQUIRES:
1. the alpha subunit to binmd GDP.
2.THE ALPHA SUBUNIT TO BIND GTP.
3.THE HYDROLYSIS OF BETA SUBUNITS.
4.THE ALPHA -SUBUNIT TO PHOSPHORYLATE DOWNSTREAM TARGETS.
2.
EACH OF THE FOLLWING IS REQUIRED TO BE ACTIVE DURING FATTY ACID BIOSYNTHESIS EXCEPT ONE:
1.TRICARBOXYLIC ACID CYCLE
2.PYRUVATE DEHYDROGENASE.
3.AMINO ACID CATABOLISM.
4.BETA OXIDATION.
5.GLUCOLYSIS.
3.
COUPLED RESPIRATION REQUIRES EACH OF THE FOLLWOING EXCEPT ONE .wHICH ONE IS THE EXCEPTION?
1.ADP
2.OXYGEN
3.CARBONDIOXIDE.
4.ELECTRON DONOR.
5.INORGANIC PHOSPHATE
4
WHICH OF THE FOLLOWING SECRETES INSULIN LIKE GROWTH FACTOR 1 AND WHAT STIMULATES THE SECRETION?
1.ANTERIOR PITUITARY,INCREASING GROWTH HORMONE IN BLOOD.
2.ANTERIOR PITUITARY ,INCREASING GRH IN BLOOD.
3,KIDNEY,INCRESING GROWTH HORMONE IN THE BLOOD.
4.LIVER ,INCRESING GROWTH HORMONE IN THE BLOOD.
5.LIVER,INCREASING TSH IN THE BLOOD.
5
A PERSON WITH A HISTORY OF ANABOLIC STEROID ABUSE BUT HAS RECENTLY STOPPED IS LIKELY TO EXHIBIT EACH OF THE FOLLOWING CHARACTERISTICS EXCEPT?
1.sterility
2.low fsh levels
3.low testosterone levels
4.decresed number of spermatids.
6.
A PRACTIONER ADMINISTERS A 90:10 NITROUS OXIDE -OXYGEN MIXTURE TO A PATIENT .Which of the following conditions is likely to occur?
1.metabolic acidosis.
2.respiratory acidosis.
3.metabolic alkalosis.
4.respiratory alkalosis
7.which of the follwong describes the a major effect of sicle cell anemia?
1.absence of biphosphoglycerate binding of hemoglobin
2.substitution of 2 proximal histidines.
3.a p-50 value for haemoglobin similar to that of myoglobin.
4. a decreased solubilty of the deoxy form of haemoglobin.
8.
excessive use of diuretics lead to:
1.metabolic acidosis.
2.respiratory alkalosis.
3.metabolic acidosis.
4.respiratory acidosis
