What energy systems produce energy anaerobically? Answer -
phosphocreatine system and anaerobic glycolysis system
What energy systems produce energy aerobically? Answer - aerobic glycolysis,
kreb cycle, and electron transport chain
Energy for exercise involves the ______ of ________ to fuel muscle
contractions Answer - energy for exercise involves hydrolysis of ATP to fuel
muscle contractions
How do muscle contract? Answer - Muscles contract through a series involving
1. electrical stimulation at the neuromuscular junction 2. propagation of an
action potential across the sarcolemme 3. excitation contraction coupling (the
release of calcium from the sarcoplasmic reticulum and actin myosin
crossbridge formation (creates tension) 4. the cycle continues wiht muscle
relaxation following reuptake of calcium by the sarcoplasmic reticulum
How many seconds of energy (ATP) is stored in the muscles? Answer - 8-10
seconds
The phosphocreatine system involves ........ Answer - the breakdown of
Phosphocreatine (PCr) to Creatine (Cr) and free Phosphate (P) The P combines
with ADP in the cell to generate ATP
Phosphocreatine (PCr) is stored in the Answer - skeletal muscle
,Phosphocreatine (PCr) can be consumed via Answer - muscle foods such as
beef, pork and fish
The theory behind creatine supplementation is Answer - that boosting Cr
stores may enhance rapid ATP production and generation
One reason the Phophocreatine System produces energy so quickly is that ....
Answer - it occurs when oxygen is not present it is an anaerobic process
The glycolytic system uses what kind of substrates in metabolism? Answer -
carbohydrate substrates
Carbohydrates are available in the _______ in the form of ______ Answer -
carbohydrates are available in the blood in the form of glucose
carbohydrates are stored in the _____ and ____ in the form of ____ Answer -
carbs are stored in the liver and muscle in the form of glycogen
the glycolytic system can produce energy in ____ and ____ environments
Answer - the glycolytic system can produce energy in anaerobic and aerobic
environments
Anaerobically glycolysis can produce ATP for approximately ______ to ___
minutes Answer - Anaerobically glycolysis can produce ATP for approximately 1
to 3 minutes
1 molecule of glucose produces a net gain of ___ ATP in anaerobic
environments Answer - 1 molecule of glucose produces a net gain of _2 ATP in
anaerobic environments
, Aerobically when oxygen is available glycolysis can produce ATP for _______
Answer - Aerobically when oxygen is available glycolysis can produce ATP for
longer than an hour
1 molecule of glucose produces a net gain of ____ to _____ ATP in aerobic
environments Answer - 1 molecule of glucose produces a net gain of __32__ to
___38_ ATP in aerobic environments
Anaerobic glycolysis produces ATP through a pathway ending at ____ Answer -
Anaerobic glycolysis produces ATP through a pathway ending at pyruvate
Anarobic glycolysis produces Answer - Anaerobic glycolysis produces ATP,
NADH production and Hydrogren ions (H+)
hydrogen ions (H+) have two fates, what are they? Answer - hydrogen ions
produced by anaerobic glycolysis can either combine with pyruvate to form
lactate or are oxidized by the electron transport chain (ETC)
what is the fate of lactate? Answer - lactate can be recycled as a glycolytic
substrate via the cori cycle
the cori cycle takes place in the ________ Answer - the cori cycle takes place in
the liver
What is the lactate threshold? Answer - the lactate threshold is when the
production of hydrogen ions exceeds the livers capacity of the liver to clear
lactate and when pruduction of lactate exceeds clearance this is when the
lactate threshold occurs
