Aerobic and anaerobic pathways. instant energy comes from anaerobic pathways (Glycolysis) and long durations come from aerobic pathways (Krebs cycle).

What is the role of myosin APT ase in muscle contraction?

Myosin ATPase hydrolyze ATP into ADP+pi and yielding the energy required for muscle contraction.


At peak levels of muscle exertion the mitochondria can supply what?

At peak levels of muscle exertion, mitochondria can supply energy to the muscles by producing ATP through the process of aerobic respiration. This provides the necessary energy for muscle contraction and is vital for sustaining intense physical activity. Additionally, mitochondria play a role in regulating metabolism and maintaining cellular homeostasis.


What role does the heart play in exercise?

the role of the heart is to supply the working muscle with oxygen and energy


What role does calcium and oxygen have in muscle contraction?

Calcium plays a key role in muscle contraction by binding to troponin, which allows tropomyosin to move and expose actin binding sites for myosin. Oxygen is needed in the process of cellular respiration to produce ATP, which is the energy source for muscle contraction to occur efficiently. Oxygen is also used to replenish ATP and remove waste products during muscle activity.


What is the role of the triad in muscle contraction?

The triad in muscle contraction consists of a T-tubule and two terminal cisternae of the sarcoplasmic reticulum. It plays a critical role in muscle excitation-contraction coupling by allowing the action potential to be rapidly transmitted deep into the muscle fiber and triggering the release of calcium ions from the sarcoplasmic reticulum, which are essential for muscle contraction.


What is the role of nutrient in sport?

Every nutrient has it's own role in sports: carbohydrates - energy supply (immediate and store) fats - energy supply (slow moving sports) proteins - increase muscles (size) vitamin - c - heals wounds & fights infection k - clots blood (cuts) minerals - calcium - muscle contraction (and bone hardness) iron - forms haemoglobin (carries oxygen to cells) potassium - muscle contraction water - helps keep body cool (sweating) But fibre I do not know. I know that it aids digestions and keeps the bowl functioning healthily, but I do not know how this plays a role in sports. Hope this helps! Dated: 8th November 2010 By: Jo :)


Is aids in muscle contration a function of protein?

Yes, the role of protein in muscle contraction is essential. Proteins, specifically actin and myosin, are the main components involved in the contraction of muscle fibers. These proteins interact in a process that generates force, resulting in muscle contraction.


Role of ionic calcium in muscle contraction?

Ionic calcium plays a crucial role in muscle contraction by binding to the protein troponin, which then allows for the movement of tropomyosin, enabling myosin heads to bind to actin filaments and form cross-bridges. This process ultimately leads to muscle fiber contraction.


What is the function role of t tubules?

Enhance cellular communication passage for nervous stimulation during muscle contraction.


What role does the nervous system play in muscle contraction?

controls the muscles by the motor nurons.


Role of ATP in energy coupling and transfer?

ATP is the primary energy currency of the cell that stores and transfers energy in chemical reactions. It plays a crucial role in energy coupling by providing the necessary energy to drive endergonic reactions in the cell. ATP hydrolysis releases energy that is used to power cellular processes, such as muscle contraction, active transport, and biosynthesis.


Which ion is stored in the sarcoplasmic reticulum?

Calcium ions are stored in the sarcoplasmic reticulum of muscle cells. These ions play a crucial role in muscle contraction by triggering the release of more calcium ions into the muscle cell, leading to the contraction of the muscle fibers.
