MACROMOLECULES

Question 1

TRUE OR FALSE
MONOMERS ARE THE BUILDING BLOCKS OF MACROMOLECULES?

Answer 1

TRUE.
MONOMER ARE WHAT MAKE UP MACROMOLECULES THEY ARE REFERRED TO AS “BUILDING BLOCKS”

Question 2

TRUE OR FALSE

THE PROCESS OF HYDROLYSIS WORKS WITH ENZYMES +WATER TO BREAK DOWN MACROMOLECULES?

Answer 2

TRUE.

HYDROLYSIS IS REFERRING TO WHEN A MACROMOLECULE IS SURROUNDED BY WATER + ENZYMES IT IS BROKEN DOWN

Question 3

MATCH THE CORRECT MACROMOLECULES WITH THE MONOMER THEY ARE MADE OF:

Answer 3

CARBOHYDRATES = MONOSACCHARIDES
LIPIDS = FATTY ACIS +GLYCEROL
PROTEINS= AMINO ACIDS
NUCLEIC ACIDS= NUCLEOTIDES

Question 4

WHICH OF THE FOLLOWING ARE CARBOHYDRATES?

Answer 4

-GLUCLOSE
-SUCROSE
-FRUCTOSE
-LACTOSE
-CELLULOSE

IT IT ENDS IN -OSE IT IS LIKELY A CARBOHYDRATE

Question 5

WHICH OF THE FLOOWING MACROMOLECULES ARE KNOWN TO BE THE PRIMARY SOURCE OF ENERGY?

Answer 5

CARBOHYDRATES
CARBOHYDRATES PROVIDE ENERGY B/C THEY ARE EASILY CONVERTED INTO GLUCLOSE. GLUCLOSE IS INVOLVED IN METABOLIC ENERGY

Question 6

WHICH OF THE FLOOWING MACROMOLECULES ARE FOUND IN THE CELLULAR MEMBRANE + CONTROL WHAT COMES IN +OUT OF THE CELL?

Answer 6

LIPIDS

PHOPHOLIPIS FORM A BI-LAYER THAT SURROUND THE CELL+ CONTROL WHAT COMES IN +OUT OF THE CELL

Question 7

WHICH PART OF THE LIPID IS HYDROPHILIC?

Answer 7

THE GLYCEROL

Question 8

WHICH OF THE FOLLOWING ARE NUCLEIC ACIDS?

Answer 8

DEOXYRIBONUCLEIC AICD
RIBONUCLEIC ACID

*BOTH RNA+ DNA ARE THE ONLY NUCLEIC ACIDS. THEY ARE MADE UP OF NUCLEOTIDES

Question 9

WHICH OF THE FOLLOWING ENZYMES BREAKS DOWN POLYSACCHARIDES INTO SIMPLER SUGARS IN OUR DIGESTIVE SYSTEM?

Answer 9

AMYLASE

SALIVA HAS AN ENZYME CALLED AMYLASE THAT HELPS BREAKDOWN COMPLEX CARBS INTO SUGARS.

Question 10

TRUE OR FALSE.

ENZYMES ACT AS BIOLOGICAL CATALYSTS THAT INCREASE THE RATE OF A REACTION BY REDUCTING THE ACTIVATION ENERGY NEEDED TO BEGIN A REACTION?

Answer 10

ENZYMES ACT AS CATALYST IN THE BODY. THEY WORK BY REDUCING THE ACTIVATION ENERGY NEEDED TO START A REACTION.

IT IS ALSO IMPORTANT TO KNOW THAT ENZYMES CAN BE REUSED, THEY ARE NOT DESTROYED IN THE REACTION.

Question 11

WHICH OF THE FOLLOWING IS AN ENZYME THAT BREAKS DOWN FATS IN THE DIGESTIVE SYSTEM?

Answer 11

LIPASE.
LIPASE IS A TYPE OF DIGESTIVE ENZYME THAT HELPS BREAKDOWN FATS FOR EASIER DIGESTION.

Question 12

WHICH OF THE FOLLOWING ENZYMES BREAKDOWN PROTEIN?

Answer 12

PEPSIN
PEPSIN IS A DIGESTIVE ENZYME THAT BREAKS DOWN PROTEINS INTO PEPTONES. ENZYMES THAT BREAK DOWN PROTEINS ARE KNOWN AS PROTEASES.

Question 13

TRUE OR FALSE
CATALYST DO NOT START A CHEMICAL REACTION, THEY SPEED UP A CHEMICAL REACTION. A CATALYST IS AN ENZYME.

Answer 13

FALSE

Question 14

TRUE OR FALSE
AN ENZYME IS A TYPE OF PROTEIN

Answer 14

TRUE.
MOST ENZYMES ARE ALMOST ALWAYS A PROTEIN

Question 15

WHICH OF THE FOLLOWING ARE TRUE STATEMENTS?

Answer 15

• METABOLISM IS DIVIDED INTO TWO OPPOSITE PROCESSES ANABOLIC + CATABOLIC

-ANABOLISM IS THE PROCESS OF BUILDING UP

-CATABOLISM- BREAKING THINGS DOWN

*BREAKING COMPLEX SUBSTANCES DOWN INTO SIMPLER SUBSTANCES. BREAKING FOOD DOWN LIKE PROTEINS + FATS IN OUR DIGESTIVE SYSTEM IS CATABOLISM.
