What does the mitochondria do in muscle cell?
Mitochondria in muscle cells produce energy through a process called cellular respiration, generating ATP (adenosine triphosphate) that fuels muscle contractions. This energy production enables muscle cells to sustain prolonged contractions during physical activities.
What is the pathways of the blood?
the blood muscle
What pathways to regenerate ATP during muscle activity is the fastest?
anaerobic glycolysis and lactic acid formation
What is the primary source of energy for muscle during aerobic activities?
glucose
The first step toward generating a skeletal muscle contraction is The first step toward generating a skeletal muscle contraction is?
stimulation of the muscle by a nerve ending.
Why does exercise generate Hydrogen ions?
During exercise, muscles produce energy through various metabolic pathways, such as glycolysis and the citric acid cycle. These pathways generate adenosine triphosphate (ATP) for muscle contractions, resulting in the production of hydrogen ions as byproducts. This can lead to an increase in acidity in the muscle cells, contributing to muscle fatigue.
Do cardiac muscle makes most of its ATP via anaerobic pathways?
no
During isometric contraction the energy used appears as movement?
During isometric contraction, no movement occurs, as the muscle is generating force without changing in length. The energy used is still expended by the muscle, but it is not converted into movement. Instead, the energy is dissipated as heat within the muscle tissue.
The first step toward generating a skeletal muscle contraction?
stimulation of the muscle by a nerve ending.
Is ATP the most abundant energy source for muscle contraction?
Yes, ATP is the primary energy source for muscle contraction. During intense exercise, ATP stored within the muscle cells is rapidly depleted and must be regenerated through metabolic pathways to sustain muscle contractions.
Which type of muscle is suited for endurance activities?
Red Muscle is suited for endurance activities.
The role of atp in muscle contraction is to supply energy for?
Aerobic and anaerobic pathways. instant energy comes from anaerobic pathways (Glycolysis) and long durations come from aerobic pathways (Krebs cycle).
