Class Cells to Systems
Metabolism
Break down of carbs, fats and proteins for energy production that is stored
as ATP and electron carriers (NADH/ NADPH/ FADH)
Waste elimination
Structure growth, reproduction and maintenance while also responding to
the environment
Enzymes help increase rate of reactions
Anabolism:
Phosphoryl group input energy transfer from ATP to reduce power inside
electron carriers (build up)
Carbs (Metab):
Glycolysis, TCA cycle, electron transport chain, oxidative phosphor ATP
function in energy transfer
Lipids/ Proteins (Metab):
Fatty acid breakdown and synthesis, amino acid degradation and nitrogen
excretion
Integration:
Relationships in the metabolism processes between carbs fatty acids and
amino acids
Products of Glucose
Metabolism/ Processes 1
, Structural synthesis of polymers
Pentose Phosphate Pathway (Ribose 5- Phosphate)
Glycogenesis (Glycogen)
Glycolysis (Pyruvate)
Citric Acid Cycle (CO2)
Anaerobic respiration (Lactate)
Electron Transport Chain (ATP)
Glycolysis (Cytosol Process):
Sweet Splitting- 6 Carbon sugar makes 2 ATP investment and becomes 2x
Pyruvate= 3 carbon sugar
4 ATP+ 2NADH+ pyruvate leave the process
Glucose:
Uses ATP to convert into Fructose 1,6 Bisphosphate turning into
Glyceraldehyde 3 phosphate and DHAP. DHAP must be converted into
G3P for PEP to form
G3P turns into PEP after using ATP and NADH
PEP + ATP= Pyruvate
Phosphate Group
Opposites attract (Negatively charged, targeted by positively charged
enzymes)
Ensures molecules stays inside the cell
They help redistribute electrons and energy so bonds can be broken or
reaction rates can be increased
Glycolysis:
Step 1-5 is glucose being phosphorylated using ATP, an unstable
substance is generated which is broken into a 3 carbon sugar
Step 6- Adding another phosphate to the 3 carbon sugar
