Cards

Term
Metabolic Processes
Definition
All the chimical reactions that occur in the body
Term
Anabolism (Dehydration synthesis)
Definition
makes larger molecules from smaller ones. requires energy makes polysaccharides, triglycerides, and proteins
Term
Catabolism (Hydrolysis)
Definition
Larger molecules broken down. Releases energy, water is consumed, used to decompose carbohydrates, lipids, and proteins
Term
Enzymes
Definition
control rate of metabolic reactions Lower energy needed to start reactions Globular proteins. Specific shapes. Not consumed in chemical reactions Substrate specific
Term
The Shape of _________ determines substrate.
Definition
active site
Term
Metabolic Pathways
Definition
Series of enzyme-controlled reactions leading to formation of a product.
Term
Things that alter enzymes
Definition
Heat, Radiation, Electricity, Chemicals, Changes in pH
Term
Cellular respiration occurs in what three series of reactions?
Definition
Glycolysis
Citric acid cycle
Electron transport chain
Term
Cellular Respiration produces?
Definition
Carbon dioxide
Water
ATP
Term
What are the 3 ATP parts?
Definition
Adenine
Ribose
3 phosphates in a chain
Term
Glycolysis is a series of 10 reactions which yields?
Definition
2 molecules of ATP for each molecule of glucose
Term
What 3 main events happen in Glycolysis?
Definition
Phosphorylation
Splitting(glucose split into two parts)
Production of NADH and ATP
Term
Anaerobic Reactions
Definition
No Oxygen
ETC cannot accept NADH
Pyruvic acid--->lactic acid
glycolysis inhibited
ATP roduction declines
Term
Aerobic Reactions
Definition
Oxygen is present
Pyruvic acid---->acetyl CoA
Begins the processes which occur in mitochondria
Term
Citric Acid Cycle
Definition
begins when acetyl CoA combines with oxaloacetic acid
series of changes end with re-creation of oxaloacetic acid
cycle repeats as long as pyruvic acid and oxygen available
Term
For each citric acid molecule:
Definition
1 ATP produced (2 per glucose)
8 Hydrogen atoms transferred to NAD+ and FAD
2 CO2 produced. 4 per glucose molecule
Term
Electron Transport Chain
Definition
NADH and FADH2 carry electrons to ETC
Series of electron carriers located in CRISTAE
Energy from electrons XFRD to ATP SYNTHASE
