CA research 1How do muscles get the energy they need to work All muscles need ATP (ATP is a ‘energy currency’) most of these cell reactions rely on the breakdown of ATP the ways to get atp are to react anaerobically or aerobically. The “ reactions form energy in the format of ATP’’ ATP (also known as adenosine tri-phosphate) is produced. Respiration is conducted from the cell membranes inside the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level

minute‚ with most of the world sure the car would be named‚ "The Panther." Although the strange name had to be explained to the public‚ Camaro fit in with other Chevy names- Corvette‚ Chevelle‚ Chevy 2‚ and Corvair. The main reason the Camaro was introduced was because of the huge success of the Ford Mustang. The Camaro was roughly the same size as the Mustang‚ a little wider and based more on performance. The Camaro is one of the last remaining muscle cars still in production today. It is only

MANY PROCESSES MUST TAKE place within the skeletal muscle fibres in order for muscle contraction to occur. The cross bridge cycle‚ process by which the muscle length is shortened as myosin heads‚ extending from the myosin filaments‚ interact cyclically in a rowing motion with the actin filament (Rayment et al. 1993)‚ is one of the crucial mechanical events required. The mechanism is initiated when an ATP molecule is bound to a myosin head. An enzyme within the head. known as ATPase‚ hydrolyzes the

Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle Your answer : a. calcium is not released from the sarcoplasmic reticulum. Correct answer: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction

Muscle Fiber contractions for our purposes begins with the arrival of action potential (action potential- is an electrical current) at the end of the axon terminal (axon terminal- the swollen distal end of the motor neuron axon). When the action potential reaches the axon terminal the action potential causes the voltage- gated calcium ion channels to open allowing calcium to flow in from extracellular fluid. The presence of calcium in the axon terminal causes synaptic vesicles (synaptic vesicles-

very similar in some ways but are very different in others. The 2005 Ford Mustang GT comes with an extra set of front headlights adding to the race car image. It is also accented in the rear by a sleek wing and retro taillights. The overall feel of the car is of something that has come from the 60’s and crossed with today’s technology‚ making the car a huge hit among many people. The 2005 Dodge Charger‚ on the other hand‚ has a very similar look to

First generation (1970–1974) The Challenger was described in a book about 1960s American cars as Dodge’s "answer to the Mustang and Camaro. It was one of two Chrysler E-body cars‚ the other being the slightly smaller Plymouth Barracuda. "Both the Challenger and Barracuda were available in a staggering number of trim and option levels" and were intended "to compete against cars like the Chevrolet Camaro and Ford Mustang‚ and to do it while offering virtually every engine in Chrysler’s inventory."

INTRODUCTION OF MUSCULAR SYSTEM. Muscles tissue do is done by the coordinated contraction and release of millions of sarcomeres‚ tiny structures within the muscles cells. Muscle activity accounts for the most of the body’s energy consumption. All muscles tissues is strong. Most is enduring‚ some of it astoundingly so. Its cells are crowded with mitochondria‚ thousands of little factories constantly turning out molecules of ATP‚ a refined fuel. There are three types of muscles that can be found in our body
