Correct Answer-rises, drops proteins Correct Answer-amides are the functional groups present in: fructose-6-phosphate, glyceraldehyde-3-phosphate, NADPH, ribose-5-phosphate Correct Answer-list all the products of the PPP: going down periodic table due to greater size and polarizability Correct Answer-Nu...

CEM 142 First Exam Latest Update Already Passed Define and give examples of open, closed and isolated systems Open system-both matter and energy can enter or leave (beaker without a lid, pour your hot drink into a mug) Closed system- the amount of matter is constant and only energy can enter or leave (cup of coffee with a lid on it) Isolated systems- neither energy nor matter would move between the system and the surroundings (Styrofoam coffee cup with a lid on) Explain the dif...

What is the third law of thermodynamics? Correct Answer The entropy of a perfect crystal is zero. What is the second law of thermodynamics? Correct Answer As a whole, the universe always tends towards increasing entropy. What is the relationship between number of microstates and entropy? Correct Answer More microstates = higher entropy What is the relationship between temperature and entropy? Correct Answer Temperature increases, entropy increases (direct) What is the relationship be...

Hydrophobic Effect correct answers _________ is the enthalpic and entropic energies contribute to the net free energy of stabilization of globular proteins. Mass Action correct answers The following equation is the analytical version of the principle of __________________________. ΔG = ΔG'o + R T lnQ, where Q = [C'][D'] / [A'][B'] Partition coefficient [It is a perturbation to the poise/balance of the participants in an equilibrium. (Take this into account to understand a...

ILTS CONTENT TEST ELEMENTARY ED(305)-PART 3/6 EXAM 2024 4 basic laws of thermodynamics - correct answer zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp syste...

AC-HPAT Physics Exam (Latest 2025 / 2026 Update) | Questions with Answers | 100% Correct | Grade A - Algonquin Question: gravitational potential energy Answer: · Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2. Question: Kinetic energ...
