Transcript Activities for Chapters 8
Activities Excersises for the chapters 8-10 Energy Class Activity Without ATP GLU + glutamic acid • • • • • NH3 ammonia = glutamine glutamic acid + ammonia glutamine ΔG = +3.4 Kcal Is this exergonic or endergonic? Does it release or consume energy? Which has greater free energy? (reactants or products) • How many ATP are needed? ACTIVITY • You are designing an experiment with an enzyme that braks down starch (amylase) that is present in your small intestine. • What temperature will be the best? • What pH will be the best? • What substrate is the best? • What other factors should you consider? ACTIVITY A X B C Q Y Z Which of these has a non-competitive inhibitor? What is "X"? What is "Q"? Which is a competitive inhibitor? ACTIVITY C A B What type of enzyme is this? What is represented by A? What is the effect of C on the enzyme in this case? Is B an example of stable or inactive? Activity • catechol + O2 → benzoquinone + H2O catechol oxidase • • • • what is the substrate? what is the enzyme? what is the product? knowing you need to heat it for the reaction to occur, does it consume energy? • Is it endergonic or exergonic? ACTIVITY • lactose + H2O → glucose + galactose • what do you expect the name of the enzyme will be? • it needs the presence of Ca+2 and/or Mg+2, what is their function? • If having this reaction in the lab, how would you stop it, considering all factors seen before? • If using negative feed back to stop it, what do you need to add to the solution where the reaction is taking place? ACTIVITIES • Is phosphorilation anabolic or catabolic? • Where in the cell does oxidative phosphorilation occur? • What organism(s) have ox. phosph.? • Where does photophosphorilation occur? • What organism(s) show photophosphorilation? • Write the formulas of both. ACTIVITY • How many ATPs are formed during aerobic respiration? • How many times more efficient is aerobic compared to anaerobic respiration? • Where does the Lactic Acid fermentation occur? • give examples of organisms that show anaerobic respiration. ACTIVITY: Fill in the blanks Cytosol Mitochondrion 2 3 1 A 4 B 5 C X Y&Z 8 9 W 7 A-C are substrate/product W-Z are stages of cellular respiration 10 1-9 are ammounts of energy produced 10 = total ammount of ATP/ molecule of glucose The End 6 ACTIVITIES • According to its nutrition, what type of organism are: – dogs – bacteria found near vents at the bottom of the ocean. – algae ACTIVITIES • According to what I'm wearing right now, what colors are being reflected and what are being absorbed? • If right after the snow storm of winter 2010 you put a white paper and a black paper over the snow. Which will melt faster the snow under it? • Why is it recommended not to wear dark colors/black in summer but it is best in winter? • Which color, yellow or green, has the lowest wavelength? ACTIVITIES Name the parts and describe what is occuring 7 4 2 3 1 8 5 6 ? What type of electron flow is this one? Name the other type. What is the difference between them? ? Activity • C4 and CAM comparison • Identify: – location in cell – name of cycle – time of day it occurs – is it spatial or temporal separation?
