EXSC 330 - Exam 1 Questions and Answers Latest Update Graded A+ **What is ATP (adenosine triphosphate) and its function in cells?** - ATP is the main energy source used by cells for most of their work. It stores potential energy extracted from food in its bonds, and energy is released when the outermost phosphate bond is broken by the enzyme ATPase. **What forms ADP in the ATP cycle?** - ADP forms when ATP combines with water (H2O). **What is the Phosphocreatine (PCr) system?** - The...

primary function of Krebs cycle - ️️to remove hydrogens and the energy associated with those hydrogens from various substrates involved in the cycle P/O ratio - ️️ratio of phosphagen bonds formed to oxygen atoms consumed Process of oxidative phosphorylation - ️️passes electrons from oxidation of a fuel source (CHO, fat, PRO) to NADH or FADH2, and finally to oxygen to produce ATP - slow but high ATP yield ATP - ️️(adenosine triphosphate) main energy source that cells use for...

Neuromuscular system produces what movement What are the two primary components of the neuromuscular system? How are they connected? nervous system and skeletal muscle connected by motor neurons Components of the central nervous system brain and spinal cord What are the major functions of the CNS control internal environment voluntary control of movement programming of spinal reflexes assimilation of experiences for memory and learning Components of the peripheral nervous sysem all nerve ce...

Anaerobic systems glycolysis ATP-PCr aerobic systems beta-oxidation Krebs Electron transport chain (ETC) Phosphocreatine System (PCr) -readily available energy -occurs within first 6-10 sec of exercise Glycolysis -breakdown of glucose or other CHO -what pyruvate changes into depends on demand of oxygen glycolysis with no oxygen pyruvate to lactic acid glycolysis with oxygen pyruvate to acetyl Co-A Beta-Oxidation -preparation of free fatty acids (FFA) into Acetyl-CoA -only produces Acetyl-C...

In theory, concurrent resistance and endurance exercise training can impair muscle protein synthesis following a bout of resistance exercise. The proposed mechanism to explain this inhibition is_____________________________________. AMP kinase activation of TSC2 Several mechanisms have been proposed to explain why concurrent endurance and resistance (strength) training impedes strength development compared to strength training alone. Which of the following mechanisms have NOT been proposed to e...

Which hormones are proportional to intensity during exercise Testosterone, Growth Hormone, catecholamines (NE and E) what changes in hormone concentration occur after exercise and why higher concentration due to lower hydration status up regulation an increase of active receptor sites on a tissue/cell to increase hormone response when there's low concentration down regulation an decrease of active receptor sites on a tissue/cell to increase hormone response when there's high concentration ...

ATP (adenosine triphosphate) main energy source that cells use for most of their work. potential energy extracted from food, energy stored in bonds of ATP -> outermost phosphate is released (uses ATPase) ADP forms when ___ joins with ____ ATP; H2O Phosphocreatine (PCr) system anaerobic resynthesis of ATP, uses creatine kinase (CK). ADP is phosphorylated to ATP (high levels of ADP is favored) ~10 sec max yield adenylate kinase assists in ATP regeneration 2 ADP ...
