The crossbridge cycle is the cyclical formation of links between actin and myosin. This results in the sliding of thin filaments towards the M line of a sarcomere. The myosin head undergoes conformation changes which allows it to swivel back and forth. In its low energy form, myosin has a low affinity for actin. The ATP prepares myosin for binding with actin by moving it to its high energy form position. When myosin contracts, it has a high affinity for actin.

The Crossbridge cycle is a series of molecular events that occur after excitation of a sarcolemma what is a Crossbridge?
A crossbridge refers to the temporary connection formed between the myosin heads of thick filaments and the actin filaments of thin filaments during muscle contraction. This interaction occurs as part of the crossbridge cycle, where myosin heads bind to actin, pull it inward (power stroke), and then release to bind again, facilitating muscle shortening. This process is driven by ATP hydrolysis and is crucial for the contraction of muscle fibers.
What are the key steps involved in the crossbridge cycle during muscle contraction?
During the crossbridge cycle in muscle contraction, the key steps involve the binding of myosin to actin, the power stroke where the myosin head pivots and pulls the actin filament, the release of ADP and inorganic phosphate, and the resetting of the myosin head for the next cycle.
Binding of the myosin heads sequentially prevents what?
myosin crossbridge binding
When the crossbridge of the myosin molecule forms linkages with actin filaments the result is?
When the crossbridge of the myosin molecule forms linkages with actin filaments, it leads to muscle contraction through a process known as the power stroke. This interaction causes the myosin head to pivot, pulling the actin filament inward and shortening the muscle fiber. This cycle of attachment, pivoting, and detachment continues as long as calcium ions and ATP are present, enabling sustained muscle contraction. Ultimately, this mechanism is fundamental to the sliding filament theory of muscle contraction.

Difference between rankine and brayton cycle?
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
