What is the relationships between cellular respiration muscle contraction and rigor mortis?
Cellular respiration in muscle cells produces ATP, which is essential for muscle contraction. After death (rigor mortis), ATP production stops, leading to a lack of energy for muscle relaxation. This causes muscles to stiffen due to an inability to break the cross-bridges between actin and myosin filaments.
What is commonly used to produce ATP during skeletal muscle contraction?
creatine phosphate, anaerobic cellular respiration, aerobic cellular respiration
Which process provides the energy that the cells need to contract?
The process that provides energy for muscle cell contraction is called cellular respiration. During cellular respiration, cells break down glucose and other nutrients in the presence of oxygen to produce ATP (adenosine triphosphate), which is the energy currency used by cells for various activities, including muscle contraction.
What provides the energy needed for muscle contraction?
Muscle contraction is powered by adenosine triphosphate (ATP). ATP is produced by breaking down glucose through cellular respiration, a process that occurs in the mitochondria of muscle cells. ATP provides the energy necessary for myosin and actin filaments to slide past each other, resulting in muscle contraction.
What process of cellular respiration causes muscle soreness?
When the body produces lactic acid because it doesn't have enough oxygen this makes a muscle sore.
What is the function role of t tubules?
Enhance cellular communication passage for nervous stimulation during muscle contraction.
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
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 are the product obtained during cellular anaerobic respiration human muscle cell-?
The product obtained during cellular anaerobic respiration human muscle cell water, energy and carbon dioxide.
Which one of these does not require energy is it synthesis of protein or transmission of nerve impulses or tissue respiration or muscle contraction?
tissue respiration.
What requires ATP cellular energy?
Processes that require ATP cellular energy include muscle contraction, active transport of molecules across cell membranes, and cellular respiration to generate energy in the form of ATP. Additionally, ATP is needed for biosynthesis of molecules, DNA replication, and cell division.
Which organelles should you isolate from muscle cells to study cellular resporation?
The mitochondria is the main site for cellular respiration, but just looking at the mitochondria won't work because part of cellular respiration takes place in the cytoplasm outside of the mitochondria.
