Where is cortisol released from correct answers adrenal cortex
An adipocyte contains: correct answers triglycerides and hormone receptors on the cell
membrane
The structural back bone of a steroid hormone is correct answers Cholesterol
In an oxidation reduction reactions the molecule that is the REDUCING agent is: correct answers
The molecule that donates an electron
In an oxidation reduction reaction the molecule that is the OXIDIZING agent is: correct answers
The molecule that accepts an electron
In the electron transport chain: H ion passes through the respiratory assembly allowing for the
formation of ATP and H2O: T/F correct answers True
During glycolysis what two enzymes require ATP correct answers Hexokinase and
phosphofructokinase
What is the rate limiting enzyme of glycolysis? correct answers PFK-1
What is the rate limiting enzyme of the ATP-PCr system correct answers Creatine Kinase
Process which produces 3 NADH+H, 1 FADH2, and 1 ATP for every spin cycle correct answers
Krebs cycle
process that procudes 1 NADH+H, 1 FADH2 and 1 Acetyl-CoA for every spin cylce correct
answers B-oxidation
Lactate can be the end product of this process correct answers Glycolysis
Fuels activity lasting only 3-15 seconds correct answers ATP-PCr system
Fuels activity lasting between 20 secs to 3 minutes (max) correct answers Glycolysis
Involves the oxidation of coenzyme carriers correct answers electron transport chain
What is the enzyme that converts pyruvate to Acetyl-CoA correct answers Pyruvate
dehydrogenase
Catalyzes the breakdown of ATP to ADP correct answers ATPase
Catalyzes the conversion of glucose to G6P correct answers hexokinase
, combines with acetyl CoA to form citric acid correct answers oxaloacetate
Catalyzes the conversion of pyruvate to lactate correct answers lactate dehydrogenase
What is the optimal exercise intensity for burning fat correct answers Right before lactate
threshold, around 60% VO2 max. Once past lactate threshold there is accumulation of Lactate in
the blood which blocks triglycerides from being taken from adipose tissue to be used for fuel.
Carbohydrates are stored in the body as _______________ and fat is stored as
_______________ correct answers Glycogen, triglycerides
In the electron transport chain, e- from FADH2 enters gate/pump correct answers 2
Enzymes _______ reactions. During exercise there is a _________ in core body temperature
which will __________ enzyme activity correct answers catalyze, increase, increase
During PA, cortisol release will _____________, epi release will ____________ and insulin
release will ______________ correct answers increase, increase, decrease: Cortisol stimulates
FFA mobilization to use as energy sparing blood glucose. Epi will increase the movement of
glucose from the liver. decrease insulin: insulin is how plasma glucose is moved into storage,
during activity we want to use plasma glucose, sparing blood glucose: So turn this off.
The primary fuels used by the body are fats and carbs. Some proteins can be used for fuel and
contributes to fuel used in metabolism. How? correct answers The protein Alanine is can be
converted to glucose and/or the carbon skeletons of the amino acids can be broken down and
used as intermediates in the Krebs cycle.
When metabolizing glycogen via glycolysis what is the net number of ATP produced? correct
answers 3 ATP. This is because glycogen does not need an extra ATP to convert it to G6P like
glucose does. Glucose needs ATP to activate the enzymes hexokinase and phosphofructokinase.
An RER of .85 indicates a reliance on which fuel for energy? correct answers Mixed: fat and
carbs. RER of 1: all carbs. RER of 85 and below: mostly using fat.
Relative VO2 is reported in mL/kg/min while absolute VO2 is reported in L/Min. Relative terms
are used so that individuals of different _________ can be compared correct answers body
weight.
What are the four reasons for the higher EPOC seen at high intensity exercise as compared to
moderate exercise? correct answers 1: higher body temp 2: greater depletion of PC-requiring
additional oxygen 3: greater blood lactate levels 4 higher levels of blood epi and norepi
What is the role/purpose of oxygen in the electron transport chain? correct answers Final electron
acceptor from the ETC
