8 List 3 Ways in Which Skeletal Muscle Uses Atp

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. Anaerobic glycolysis Anaerobic glycolysis and lactic acid formation Direct phosphorylation of ATP by creatine Phosphate.

Muscle Tissue Cont Muscle Metabolism Chapter Ppt Download

Most of the immediate energy supply is held in an energy pool of the compound creatine phosphate or phosphocreatine PCr which is in.

. According to Muscle Physiology from the University of California San Diego ATP supplies the energy needed by muscles to contract. Muscle cells synthesize ATP these three ways. Brain and skeletal muscle use the Glycerol Phosphate shuttle so the ATP yield from cytoplasmic NADH is less.

Chemical energy to light energyd. 1 Phosphagen 2 Glycolytic and 3 Mitochondrial Respiration. How long does it take for ATP to replenish.

There are three mechanisms by which ATP can be regenerated. Muscles attach to bones directly or through tendons or aponeuroses. Electrical energy to chemical energy.

Direct Phosphorylation of ADP by creatine phosphate. Skeletal muscles maintain posture stabilize bones and joints control internal movement and generate heat. The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards.

Graded contractions of skeletal muscle terms. Choose muscle is contracting muscle is relaxed depolarization of the sarcolemma has occurred Choose muscle is contracting. Describe three ways in which ATP is regenerated during muscle activity Learning Targets.

Exogenous ADP UTP and UDP also promoted calcium. 32 in heart liver and kidney and 30 in brain and skeletal muscle. 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.

Myosin binds to actin at a binding site on the globular actin protein. Phosphagen immediate source Anaerobic somewhat slow uses carbohydrates Aerobic slow uses either carbohydrate or fat Phosphagen. The chemical stimulates muscle relaxation by disconnecting myosin and actin.

Ironically ATP is also needed for muscle relaxation. Muscle Cells Obtain ATP From Several Sources. Skeletal muscle fibers are long multinucleated cells.

The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards. This action requires energy which is provided by ATP. OTHER SETS BY THIS CREATOR.

Heart liver and kidney use the Malate Aspartate shuttle so they get the full ATP value for cytoplasmic NADH. Start studying 3 pathways to generate ATP during muscle activity. Based on NADH yielding 25 ATP and FADH2 yielding 15 ATP.

The membrane of the cell is the sarcolemma. ATP also known as adenosine triphosphate is the primary source of energy. Learn vocabulary terms and more with flashcards games and other study tools.

The energy sources used to synthesize ATP for muscle contraction are the free ATP phosphocreatine glycolysis and cellular respiration. This system uses creatine phosphate CP and has a very rapid rate of ATP production. Chemical energy to mechanical energyb.

Energy in ATP is used to power skeletal muscle contraction. This occurs in several ways using one of three energy systems. Used when the oxygen supply is inadequate over time.

The three systems differ in the substrates used products maximal rate of ATP regeneration capacity of ATP regeneration and their associated contributions to fatigue. Low levels of ATP exist within the muscle fibers and can immediately provide energy for contraction. Start studying 3 ways ATP is produced for muscle contraction.

However the pool is very small and after a few muscle twitches will be exhausted. Learn vocabulary terms and more with flashcards games and other study tools. History ch 1 2.

- 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. Exogenous ATP induced an increase in intracellular free Ca 2 concentration with an EC 50 value of 78 31 µM. What are 3 ways a muscle fiber can use ATP.

Hydrolysis of creatine phosphate 2. The cytoplasm of the cell is the sarcoplasm. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP releasing an inorganic phosphate.

Creatine Phosphate The immediate source of energy for rebuilding ATP is the high energy molecule creatine phosphate. Learn vocabulary terms and more with flashcards games and other study tools. Solutions for Chapter 3 Problem 1DYB.

This is an example of what type of energy conversiona. ATP and Muscle Contraction. This action requires energy which is provided by ATP.

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. Start studying 3 ways the muscle cells replenish their ATP supplies. Three energy systems function to replenish ATP in muscle.

Myosin binds to actin at a binding site on the globular actin protein. Creatine phosphate metabolism anaerobic glycolysis fermentation and aerobic respiration. Three ways ATP is used in a muscle cell.

The Krebs cycle oxidative phosphorylation Page 9. What are 3 ways in which ATP is regenerated during skeletal muscle contraction. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP releasing an inorganic phosphate molecule and energy.

Light energy to mechanical energyc. Isometric and isotonic contractions. Terms in this set 26 the first way to generate ATP during muscle activity is the use of _____ _____ creatine phosphate.

Although ATP is the immediate fuel for the contraction process its concentration in the muscle cell is never high enough to sustain a long series of contractions. Skeletal muscle- replenish of ATP supply.
