Metabolism/ Processes
Created @October 23, 2024 10:25 AM

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

Reduces power inside electron carriers

Carbs (Metab):

Glycolysis

TCA cycle

electron transport chain

oxidative phosphorylation ATP function in energy transfer

Lipids/ Proteins (Metab):

Fatty acid breakdown and synthesis

amino acid degradation

nitrogen excretion



Metabolism/ Processes 1

, Integration:

Relationships in the metabolism processes between carbs fatty acids and
amino acids

Products of Glucose

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 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
