Bio 111 Lab Tamu Exam 1 Questions AndAnswers 100% Solved
DCMU - ✔✔prevents photosynthesis in system II, does not affect cellular respiration, therefore
flagella can still move
Action spectrum - ✔✔determines effective wavelengths of photosynthesis in plants
Photosynthetic pigments - ✔✔ability to change colors and use different pigments to absorb light
in photosynthesis
Chlorophyll alpha and beta, xanthophyll, and carotene - ✔✔photosynthetic pigments
Sodium bicarbonate in photosynthesis lab - ✔✔remove gases from the leaves (aspirate) and supply CO2
and water for photosynthesis
flagella move towards the light - ✔✔to perform photosynthesis
flagella moves away from the light - ✔✔because it is too hot
Higher Temperature - ✔✔Faster respiration
Are these yeast using fermentation or oxidation to produce CO2? - ✔✔Both! Living organisms
perform cellular respiration to release O2, and yeast's function is to perform fermentation.
, How do changes in enzyme concentration affect product production and enzyme activity? - ✔✔When
more substrates and enzymes bind, it creates more activity. When the binding sites are exhausted,
enzyme activity plateaus. Excess enzymes have no substrates to bond to.
How do changes in substrate concentration affect product production and enzyme activity? - ✔✔When
more substrates and enzymes bind, it creates more activity. When the binding sites are exhausted,
enzyme activity plateaus.
Excess substrates with no enzymes to bind to.
Bradford Assay - ✔✔spectroscopic analytical procedure used to measure the concentration of protein
in a solution
Z Buffer - ✔✔promotes the reaction between B-gal and ONPG by optimizing the pH of the sample
How to calculate enzyme activity? - ✔✔(Absorption (aka A420)/time)x 1,000
Cellular Respiration - ✔✔the process by which cells use oxygen to produce energy from food
Glycolysis - ✔✔the breakdown of glucose by enzymes, releasing energy and pyruvic acid. (step one
of cellular respiration)
Anaerobic respiration - ✔✔no oxygen, fermentation,
Aerobic Respiration - ✔✔oxygen available, in mitochondria, produces ATP
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
