MCAT PT 6 Chem Phys

Practice from Chem / Phys topics of PT 6

Coenzyme: Non-protein molecules required by an enzyme in order to function
Focal Length Of The Relaxed Eye Is: The distance from the lens to the retina
If pH > pKA: there must be more: Base than acid
Ksp will not change if: Temperature doesn't change
If An Inhibitor Causes A Km To Stay The Same, But Lowers The Vmax, It Is Considered To Be: A non-competitive inhibitor
A Competitive Inhibitor Will Not Change VMax But Increase: The km of an enzyme
Lysine And Arginine Are: Positive at biological conditions
Serine And Threonine Are Nucleophilic And: Negatively charged
Methionine And Proline Are Hydrophobic And: Have no charge
In Order To Interact With DNA Polymerase Holoenzyme That Interacts With The Negatively Charged Phosphate Sugar Backbone, You Need To Use A Cofactor That Is: Positively charged, like Zn+
The General Equation To Use For Flow Of Fluids Is: V = IR
Destructive Interference Occurs When: Two waves meet out of phase, or when the peak of one meets the trough of the other
Destructive Interference Will Occur When The Path Length Between Two Interfering Waves Is: A half-integer multiple of the wavelength
Frequency, f = c / λ, where c = 3.0 x 10^8 m/s
Buffers Are Solutions That Contain: A weak acid and its conjugate base
Buffers Are Effective When The pH Of The Solution Is Within: One pH unit of the pKa of the acid
A Buffer Is Most Effective When There Are Equal Amounts Of: Acid and its conjugate base, aka when pH = pKa
A Reaction With A Greater Reduction Potential Is: More favorable

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then tap the card to flip it. If you knew the answer, tap the green Know box. Otherwise, tap the red Don't know box.

When you've placed seven or more cards in the Don't know box, tap "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just tap on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
