Homeostasis
This term describes the maintenance of a constant internal environment at rest.
What is homeostasis?
coordinates the response to maintain homeostasis.
What is the control center?
The main energy currency of cells.
What is ATP?
This threshold represents the work rate at which blood lactate rises disproportionately
What is lactate threshold?
This fuel is the primary energy source during low-intensity exercise
What is fat?
A physiological variable that is unchanging during exercises(aerobic), but not necessarily at rest?
What is steady state?
detects changes in a physiological variable and sends signals to the control center
What is a receptor?
Reactions that release energy, such as the breakdown of glucose, are called this
What are exergonic reactions?
VO2max is considered the physiological ceiling for this
What is oxygen uptake?
The main fuel source when exercise intensity exceeds 70% of VO2 max
What are carbohydrates?
This type of feedback attempts to reverse a change in a physiological variable
What is negative feedback?
name one organ system responsible for replenishing oxygen and removing CO2
NAD and FAD play this role in metabolism by carrying electrons and hydrogen
What are electron carriers?
The lag oxygen uptake at the beginning of exercise is called this
What is oxygen deficit?
The production of new glucose via the liver
What is gluconeogenesis?
Adaptation to heat stress that improves sweat production and composition is called this.
What is acclimation?
This measures how well a control system maintains homeostasis
What is gain?
The enzyme that catalyzes the breakdown of phosphocreatine to resynthesize ATP is called this
What is creatine kinase?
elevated oxygen consumption after exercise, known as oxygen debt is noe termed this
What is EPOC?
The cycle of converting ATP,NADH,lacate into ATP
What is the Krebs cycle?
The failure of beta cells in the pancreas, leading to hyperglycemia, demonstrates the failure of this part of a control system.
what is the effector?
These proteins are synthesized when homeostasis is disrupted to repair damaged proteins in cells.
What are stress proteins?
The three major energy systems for ATP formation include ATP-PC, glycolysis, and the oxygen-requiring process
What is oxidative phosphorylation?
During short-term, high-intensity exercise, ATP is derived 7-% from thi nad 30% from this
The metabolic process of converting fats into ATP.
What is beta oxidation?
