Muscle Metabolism Flashcards
What is metabolism?
set of chemical processes that occur within a living organism to sustain life
What are the two main metabolic processes
anabolism and catabolism
___________ = producing larger molecules from smaller molecules; molecular synthesis
___________ = breakdown of larger molecules into smaller molecules: energy production, cellular recycling, garbage removal
anabolism
catabolism
carbs, fats, and proteins are broken down via catabolism to produce _________
co2, h2o, and nh3
proteins, lipids, and nucleic acids are built via anabolism by _________
amino acids, sugars, and fatty acids
anabolic reactions ______ energy which catabolic reactions _______ energy
use
create
______ and _______ use energy to create glycogen

______ and _____ use energy to create protein
amino acids and amino acids
glycogen yields energy when broken down into _______
glucose
triglycerides yield energy when broken down into ______- and ______
glycerol and fatty acids
protein yields energy when broken down into _______
amino acids
What are the main metabolic functions? (4)
1 - energy production
2 - molecular synthesis
3 - molecular breakdown
4 - signaling and homeostatic maintenance
energy production is accomplished via?
glycolysis
TCA cycle
oxidative phosphorylation
molecular synthesis is accomplished via?
anabolism
- DNA/RNA
- proteins, lipids, and glycogen
- synthesis of AA, steroids, cofactors, etc.
- repairs to DNA/cell membranes, etc.
