During everyday activities and light exercise, the mitochondria of muscle fibers produce ATP in a process called aerobic respiration. Aerobic respiration requires the presence of oxygen to break down food energy (usually glucose and fat) to generate ATP for muscle contractions.

Which processes use ATP as an energy source in skeletal muscle quizlet?
Muscles regenerate ATP in three ways: direct phosophorylation using the following: creatine phosphate, anaerobic respiration, and aerobic respiration.
What is ATP used for in skeletal muscle?
Muscle cells can use both fatty acids and glucose for their aerobic respiration. ATP is used for two things in muscle cells: active transport of calcium (Ca++) and movement of motor proteins.
Which process uses ATP as a source of energy?
The mitochondria plays a major role in ATP production in the process of aerobic respiration. ATP is the molecule that makes it possible for organisms to sustain life and reproduce.
What process provides the most ATP for skeletal muscle to use as energy?
Cellular respiration plays a key role in returning the muscles to normal after exercise, converting the excess pyruvate into ATP and regenerating the stores of ATP, phosphocreatine, and glycogen in the muscle that are required for more rapid contractions.
What is ATP used for in the process of muscle contraction quizlet?
ATP binds to myosin causing it to change position and attach to actin and pull, causing muscles to contract. This allows muscles (even the heart) to move.
How is ATP used in muscle contraction quizlet?
ATP energy is used to detach the myosin head from it’s binding site on the actin filament during muscle contraction. When the glycogen system is hydrolyzed it releases energy; the phosphate from ATP hydrolysis is used to phosphorylate creatine to creatine phosphate.
How is ATP used during the muscle contraction process?
ATP is critical for muscle contractions because it breaks the myosin-actin cross-bridge, freeing the myosin for the next contraction.
Which processes in muscle contraction require ATP?
ATP is required for the process of cross-bridge cycling which enables the sarcomere to shorten. The steps of cross-bridge cycling are as follows: When ADP** is bound to myosin heads, they are able to bind to actin filaments of the adjacent myofibril to form a cross-bridge.
How is energy produced in skeletal muscle?
The energy is derived from adenosine triphosphate (ATP) present in muscles. Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources, namely creatine phosphate (CP) and muscle glycogen.
Why ATP is only source of energy?
ATP is the main source of energy for most cellular processes. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.
How is ATP used it is used as?
It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP.
Which process releases the most energy in the form of ATP?
The process which produces the most energy in the form of ATP is the Krebs cycle- also known as the citric acid cycle.
What are three main sources of ATP available for human muscle cells?
Humans have three main sources of ATP: ATP already in muscles, ATP made by lactic acid fermentation, and ATP produced by cellular respiration. At the beginning of a race, the body uses all three ATP sources, but stored ATP and lactic acid fermentation can supply energy only for a limited time.
What are the three processes used to generate energy for skeletal muscle contraction?
ATP provides the energy for muscle contraction. The three mechanisms for ATP regeneration are creatine phosphate, anaerobic glycolysis, and aerobic metabolism.
Which of the following processes produces 36 ATP?
The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose.
