Exam #2: True or false questions Flashcards
Lipid storage is at least 50 times as much (in kcal of energy) as glycogen storage in the body even in a lean adult
true
The Tricarboxylic cycle, the citric acid cycle, the Kreb’s cycle are three differing metabolic functions important for producing energy from foodstuffs
false
Within the mitochondrion, theATP formed along the electron transport chain a created by the process called oxidative phosphorylation
true
Fat provides more kilocalories per gram than carbohydrate, but oxidation requirements for fat are greater than oxidation requirements for carbohydrate, making fats less efficient as an energy source per unit of oxygen
true
The process of converting liver or muscle glycogen into glucose-1-phosphate is referred to as glycogenesis
false
Fast-twitch muscle fibers are best suited for glycolytic energy production
true
During near-maximal exercise, significant amounts of lactic acid are generated by the ATP-PCr energy system
false
An aerobically trained athlete will have a higher RER during exercise of low to medium intensity than a lesser trained, untrained, or an anaerobically trained athlete
false
Accumulation of lactate in the blood is determined by the balance between lactate production and lactate clearance
true
Protein is not used at all for energy production
false
Fatty acids are soluble in blood
false
Increased carnitine and carnitine acyl tranferase increases the speed of carbohydrate transport in sacroplasm.
false
Creatine kinase is needed to resynthesize ATP from ADP by phosphorylation, and is boundto the M line proteins on myosin filaments
false
During exercise, gluconeogenesis in the liver oxaloacetate since dependence of fats (i.e. lack of carbohydrate) and depleted oxaloacetate causes the results of fat metabolism to produce ketone bodies
true
