Item 11 84 Figure 17 10 shows the eflects of temperature and hydrogen on concentration on the ability of hemoglobin to bind exygen This exercise examines this Sgure more thoroughly demonstrating the significance of shits in the hemoglobin ooxygen saturation curves My Answers Give Up Completed 20°C (increased affinity) Part K 100 According to Figure 17.10b, at a pt of 7.A, how much hemoglobin is unloaded in the tissue? 80 12% 24% 56% 72% 95% 37 C (body temperature) 60 40 (decreased affinity) 20 y Answers Sive 0 20 40 60 80 100 Po, Imm Hg) Part L According to Figure 17.10b, at a pll of 72, how much hemoglobin is unloaded in the tissue? (a) Efects of temperature pH 7.6 (increased affinity) 12% 100 24% pH . 740 95% 60 40 pH 7.20 (decreased affinity) Part M 20 This question w bo shown after you complete previous questions 0 20 4 60 80 100 Po, (mm Hg) (b) Eftects of pH This quesson will be shown fter you complete previous questions)

Explanation / Answer

answer to par k - option d

answer to par l - option c

if the ph shifts from 7.4 to 7.2 i.e. more acidic. the curve drifts to the right the resting cell po2 was 40mmhg and ph is 7.2 so oxygen satiration is 75% but if ph drifts frto 7.2 the percent saturation was 68 % which means hbo2 delivers 13 % more oxygen
