Exercise Metabolism
This is the lag in oxygen uptake at the beginning of exercise
What is oxygen deficit?
This molecule is known as the primary energy currency of the cell, storing and transferring energy for cellular processes.
What is ATP (adenosine triphosphate)?
This is the process of converting food into usable energy for cell work
What is bioenergetics ?
What is the regulation of energy metabolism?
The complex biological process by which an organism maintains a balanced energy by controlling the rate of energy produced and used.
These molecules are the primary building blocks of proteins.
What are amino acids?
In Steady State all energy needed is provided by?
What is aerobic metabolism?
What is it called when ATP releases energy when this type of bond is broken
What is a high-energy phosphate bond?
These vitamins provide electron carriers for metabolism
What are B-Vitamins?
This hormone increases during exercise and stimulates glycogen breakdown in the liver to release glucose into the bloodstream.
What is glucagon?
What is the production of lipids from other substrates called?
What is Lipogenesis?
In metabolism, what is oxygen taken in above resting values after exercise?
What is Oxygen Debt?
When one phosphate group is removed from ATP, this molecule is formed.
What is ADP?
Plants convert this from sunlight
What is Carbohydrates?
This process describes the formation of glucose from non-carbohydrate sources such as amino acids, lactate, or glycerol
What is gluconeogenesis?
This process breaks down fatty acids to generate acetyl-CoA for the Krebs cycle
What is beta-oxidation?
These are the two things taking place during the rapid portion of EPOC
What are resynthesis of stored PC and replenishing muscle and blood oxygen stores?
Cells regenerate ATP from ADP and inorganic phosphate using energy from this molecule in aerobic respiration.
What is Glucose?
These are the two exercise-related factors that alter enzyme activity
What are temperature and pH?
This point during exercise intensity is characterized by a rapid accumulation of lactate in the blood.
What is the lactate threshold?
Lipids are primarily stored in this form in the body.
What are triglycerides?
This is the purpose of measuring lactate threshold
What is predicting performance or planning a training program?
ATP provides energy to fuel active transport by binding and hydrolyzing at this specific part of a membrane protein.
What is the ATP-binding site?
How do proton gradients drive ATP synthesis?
What is proton gradients are established by the electron transport chain in the mitochondria.
This adaptation from aerobic training increases the capacity to oxidize fat and delay glycogen depletion.
What is increased mitochondrial density?
This type of protein acts as a catalyst to speed up biochemical reactions.
What is an enzyme?
