10 4 Skeletal Muscle Metabolism And 10 4b Oxygen Debt Flashcards Quizlet

This is an example of what type of energy conversiona.

. Chemical energy to light energyd. There are three mechanisms by which ATP can be regenerated. List the energy sources used to synthesize ATP for muscle contraction.

Anaerobic glycolysis Anaerobic glycolysis and lactic acid formation Direct phosphorylation of ATP by creatine Phosphate. ATP and Muscle Contraction. Describe three ways in which ATP is regenerated during muscle activity Learning Targets.

The energy sources used to synthesize ATP for muscle contraction are the free ATP phosphocreatine glycolysis and cellular respiration. In rat skeletal myotubes a tetanic stimulus 45 Hz 400 1-ms pulses rapidly increased extracellular levels of ATP ADP and adenosine monophosphate AMP after 15 s to 3 min. Electrical energy to chemical energy.

Energy in ATP is used to power skeletal muscle contraction. Within a muscle fiber are myofibrils which are also arranged in bundles. 32 in heart liver and kidney and 30 in brain and skeletal muscle.

Skeletal muscle fibers can be quite large compared to other cells with diameters up to 100 μm and lengths up to 30 cm 118 in in the Sartorius of the upper leg. 1 Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke Three ways ATP is used in a muscle cell. The three systems differ in the substrates used products maximal rate of ATP regeneration capacity of ATP regeneration and their associated contributions to fatigue.

ATP must be synthesized in muscle cells to replace ATP used for muscle contraction. The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP releasing an inorganic phosphate molecule and energy.

What are 3 ways a muscle fiber can use ATP. This system uses creatine phosphate CP and has a very rapid rate of ATP production. This occurs in several ways using one of three energy systems.

Creatine phosphate has a high energy _____ bond. Chemical energy to mechanical energyb. - in a sarcomere unit ATP is used for the sliding filament mechanism - ATP-ase pump uses ATP to remove Ca2 from the cytoplasm so there is not an abundance left over to cause uncontrollable muscle contraction.

Individual myofibrils contain the structurally distinct regions. Light energy to mechanical energyc. These fibers are quick and powerful but fatigue rapidly.

Exogenous ATP induced an increase in intracellular free Ca 2 concentration with an EC 50 value of 78 31 µM. ATP is synthesized by hydrolysis of creatine phosphate glycolysis and the Krebs cycle and oxidative phosphorylation. How long does it take for ATP to replenish.

Exogenous ADP UTP and UDP also promoted calcium. What are 3 ways in which ATP is regenerated during skeletal muscle contraction. Solutions for Chapter 3 Problem 1DYB.

Choose muscle is contracting muscle is relaxed depolarization of the sarcolemma has occurred Choose muscle is contracting. This action requires energy which is provided by ATP. Direct Phosphorylation of ADP by creatine phosphate.

Creatine phosphate metabolism anaerobic glycolysis fermentation and aerobic respiration. Three ways ATP is used in a muscle cell. Direct Phosphorylation of ADP by creatine phosphate.

The first way to generate ATP during muscle activity is the use of _____ _____ creatine phosphate. Then what are three ways ATP is regenerated during muscle activity. White muscle fibers mainly use glycolysis for synthesizing ATP.

Myosin binds to actin at a binding site on the globular actin protein. Learn vocabulary terms and more with flashcards games and other study tools. The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards.

Based on NADH yielding 25 ATP and FADH2 yielding 15 ATP. This action requires energy which is provided by ATP. Having many nuclei allows for production of the large amounts.

Phosphagen immediate source Anaerobic somewhat slow uses carbohydrates Aerobic slow uses either carbohydrate or fat Phosphagen. What are 3 ways ATP is produced for muscle contraction. Low levels of ATP exist within the muscle fibers and can immediately provide energy for contraction.

However the pool is very small and after a few muscle twitches will be. Start studying 3 ways the muscle cells replenish their ATP supplies. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP releasing an inorganic phosphate.

Brain and skeletal muscle use the Glycerol Phosphate shuttle so the ATP yield from cytoplasmic NADH is less. 1 Phosphagen 2 Glycolytic and 3 Mitochondrial Respiration. Myosin binds to actin at a binding site on the globular actin protein.

100 2 ratings The muscle tissue is composed of bundles of muscle cells called muscle fibers. Heart liver and kidney use the Malate Aspartate shuttle so they get the full ATP value for cytoplasmic NADH. Because skeletal muscle cells are long and cylindrical they are commonly referred to as muscle fibers or myofibers.

Creatine phosphate is stored in. Group of answer choices intracellular calcium levels are high Choose muscle is contracting muscle is relaxed sarcomeres shorten due to sliding filament theory Choose muscle is contracting muscle is relaxed ATP is attached to mysoin. Myofibrils have thin filaments c.
