Document Summary
Cell and system activities (e. g. red blood cells, renal) Our currency to pay for activities (atp breakdown)(reversible) 3atp < > 2adp + pi + energy. How we make the currency (doesn"t go both ways) + adp + pi > atp + co2 + h2o + heat (reverse of equation. Glucose is also known as sugars and carbohydrates. Co2 + h2o < > hco3- + h+ Products of #2 ph (triangle) / acid issue > trade offs!! Relatively stable maintenance of a body parameter (aka dynamic constancy) Set point (sp): goal range (start of graph at 90) Steady state (ss): maintaining at sp (right before meal and after dinner at constant) H. control system: interconnected components that work together to keep at sp. At ss, not changing requires energy (e) Negative feedback = opposite of d = goes toward ss. Positive feedback = continue with d (same direction as d) = moves away from ss.
