ECPI BIO 111 Ch:4 Exam Questions With 100%
Verified Correct Answers.
Metabolism
sum of all chemical reactions in the body
Cellular Metabolism
Sum of all chemical reactions occurring in a cell
What are the two types of metabolic reactions
anabolism and catabolism
Anabolism
Small molecules are built into larger ones; requires energy
Catabolism
larger molecules are broken down into smaller ones; releases energy
Anabolism
Provides materials for maintenance, cellular growth and repair
Anabolism
Requires ATP made during catabolism
Example of Anabolism
dehydration synthesis
Example of Catabolism
hydrolysis
What is produced during the Anabolic process
H20
, What is catabolism used for
decompose carbohydrates, proteins, lipids
Enzymes
Greatly increase reaction rates/velocity/speed of chemical reactions
Ribosomes
Ribosomal protein + rRNA
Enzymes are
Mainly proteins but can be hybrid molecules
Another name for Enzymes
protein catalysts
Catalyze Specific reactions
Reactants have to have a specific shape for the enzyme to work on them (think lock and key)
Enzymes (protein catalysts)
Are not consumed in the reaction, so they are used repeatedly
Metabolome
all small molecules that are part of the metabolism in a cell, tissue, organ, or organism
Metabolic Pathways
Series of enzymes-controlled reactions leading to formation of a product
Rate-limiting enzyme
A regulatory enzyme that catalyzes one step of pathway typically sets rate for entire reaction
sequence
Factors that alter enzymes
