ACA Biochemistry Review Used w/ Chemistry Kahoot

Objective: Have the most x’s by the end Every Q you answer correctly, you can take 2 X’s away from a team or add 2 to your team. Cannot exceed the 10X’s you start with or dip into negatives. Every Q you get wrong, you lose an X. We continue until someone answers it correctly or we return to the first team.

An element has 13 protons and 10 neutrons. What is the atomic #?

An element has 13 protons and 10 neutrons. What is the mass #? 23

Unequal sharing of electrons POLARITY

Water molecules attracted to anything other than water ADHESION

Type of bond connecting multiple water molecules Hydrogen bond

Substance made of 2 or more compounds in equal parts SOLUTION

Water molecules attracted to other water molecules COHESION

What ALLOWS WATER TO REGULATE CLIMATE? HIGH SPECIFIC HEAT- TAKES A LOT OF ENERGY TO HEAT UP/COOL DOWN

Is water polar or nonpolar?

What causes water’s polarity? UNEQUAL SHARING OF E- BETWEEN O AND H  DUE TO OXYGEN’S ELECTRONEGATIVITY PULLING ELECTRONS TO ITSELF

What is a? A B

ACID, BASE OR NEUTRAL? EQUAL OH- AND H+ IONS NEUTRAL

What is b? A B

What causes ICE TO BE LESS DENSE THAN LIQUID WATER? H BONDS MAKE THEM SPREAD OUT

WHY DO OIL AND WATER NOT MIX? OIL HAS HYDROPHOBIC NONPOLAR BONDS AND WATER IS POLAR

Term for amount of energy needed to start a reaction ACTIVATION ENERGY

How do enzymes affect reactions? SPEED UP

How do enzymes speed up reactions? BY LOWERING THE ACTIVATION ENERGY

What happens to the reaction rate when we increase amount of enzyme? RATE INCREASES

Substance that enzymes act on SUBSTRATES

Are enzymes recycle or consumed during reactions? RECYCLED

WHAT HAPPENS WHEN ENZYMES ARE EXPOSED TO CHANGES IN PH OR HEAT DENATURE/STOP WORKING

DOES B OR C HAVE AN ENZYME PRESENT?

ARE ENZYMES SPECIFIC OR GENERAL? EXPLAIN. SPECIFIC SHAPE FOR ITS SUBSTRATE

The _________ of an enzyme is the area where the substrate binds ACTIVE SITE

WHAT IS THE REVERSE REACTION OF HYDROLYSIS? DEHYDRATION SYNTHESIS

What is protein shape dependent on? AMINO ACID SEQUENCE

What is this molecule?

TYPE OF FAT THAT CONTAINS AT LEAST 1 DOUBLE BOND UNSATURATED FAT

What is A? A A

What is the name of this?

What is B? A B

When water is added to break a polymer into monomers: HYDROLYSIS

What is C? A C

What is this molecule?

What is A? What is B?

When water is removed to make a polymer from monomers: DEHYDRATION SYNTHESIS

Enzymes ARE A TYPE OF: PROTEIN
