Bio 111 lab TAMU exam 1 latest 2023 graded A+ Accuracy a measure of how close a result matches a correct or standard value Precision a measure of variability. For example, three darts placed close together on a dartboard indicate high precision, but if this cluster of darts is far from the bullseye it would also indicate low accuracy Aliquot a portion of something (noun); or to divide or transfer a portion of something (verb). For this lab, aliquot refers to an amount of liquid Micropipette a...

Anaerobic systems glycolysis ATP-PCr aerobic systems beta-oxidation Krebs Electron transport chain (ETC) Phosphocreatine System (PCr) -readily available energy -occurs within first 6-10 sec of exercise Glycolysis -breakdown of glucose or other CHO -what pyruvate changes into depends on demand of oxygen glycolysis with no oxygen pyruvate to lactic acid glycolysis with oxygen pyruvate to acetyl Co-A Beta-Oxidation -preparation of free fatty acids (FFA) into Acetyl-CoA -only produces Acetyl-C...
