CH4 Cellular Metabolism Flashcards
Define metabolism
all chemical reactions that occur in the body, including those that obtain and use energy
What is the name for a nonprotein component that combines with an enzyme and causes it to become activated?
Cofactor
These are all examples of
producing proteins from amino acids
producing large nucleic acids from nucleotides
producing complex carbohydrates from monosaccharides
Dehydration synthesis
What two terms that describe most enzymes.
Protein and catalyst
Describe the order of cellular respiration and their functions
GLycosis
-anarobic does not need oxygen but make LITTLE atp
Citric Acid Cycle
-aerobic REQUiRES ogyden makes ALOT of atp
Electron transport chain
-aerobic
Where is chemical energy held within a molecule?
Within chemical bonds
what does glycolysis do?
Break down glucose
What are the two types of metabolic reactions?
Anabolism & Catabolism
Define Catabolism
Big molecules broken down into smaller ones
+RELEASES energy
ex breaks down carbohydrates, triglycerides, proteins, nucleic acids adds water molecules during the process?
Define anabolism
Small molecules turning to big ones
REQUIRES ENERGY
What factors alters an enzyme, describe them
cofactors
-non proteins substances
coenzyme
-small organic molecule such as Specific vitamins
denaturation
-inactivation of the enzyme
Once altered it may “never come back”
ex heat, radiating extreme PH
WHAT IS THE FUNCTION OF ENZYMES?
Controls rate of ANABOLIC/CATABOLIC REACTIONS
SPEED UP CHEMICAL REACTION
What final products does cellular respiration make?
Carbon Dioxide
water
heat
ATP
Tell me the different types of RNA describe their roles
mRNA messenger rna (nucleus)
gets a copy of the DNA to send to the ribosome so ribosome knows the instructions make the protein
tRNA transfer rna (cytoplasm)
transfer amino acids to the ribosome. picking them up and dropping them off so ribosome can build the protein
rRNA ribosomal rna
bonds with special proteins to form a ribosome
Nucleotides are what
The building blocks of DNA
