Chemistry Of Microbiology- Metabolism Flashcards
Definition of metabolism
Sum of all chemical reactions inside a cell
Catabolism
Large molecules broken into smaller ones, releasing energy
Anabolism
Small molecules assembled into larger ones, using energy
What’s NADH
Energy carriers specifically electron energy
Glucose breaking down into co2 + H2O + heat is what metabolic cycle
Catabolic
Glucose into polysaccharide is what metabolic cycle
Anabolic
What is ATP
Very important energy carrier/ coenzyme
What is ATP used for?
Intracellular signaling, DNA + RNA synthesis, purinerg ie signaling, active transport, muscle contractions
Enzyme properties
Specific substrate active site is shaped to fit, uses H2O to break up bond making products,
Can enzymes be anabolic (building things)?
Yes
Can enzymes be regulated
Yes
Can enzymes be autoregulated
Yes
What dictates what metabolic processes a cell can undergo
Enzymes
Why are metabolic/biochemical tests important
Help identify microbes and their characteristics
What is glucose?
Simple sugar, used by many organism to use as carbon
What is fermentation?
Biochemical process that gets energy from carbohydrates and doesn’t need oxygen
Anaerobic bacteria produces what fermentation
Lactic acid fermentation
What does lactic acid fermentation produce
Aspergillus and lactobacillus
What fermentation does yeast produce
Alcohol fermentation
What does deo nos fermentation produce
Saccharomyces
What does aspergillos and lactobacillus produce
Lactic acid
What does saccharomyces produce
Ethanol +CO^2, ethanol, CO^2
How can your cell create atp without creating byproduct
With oxygen calling it aerobic respiration
What element is used as an electron acceptor
Oxygen
