Where in the cross bridge cycle does ATP hydrolysis occur?
during the cocking of the myosin head
What is the crossbridge cycle?
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.
When does the myosin head cock back to store energy for the next cycle?
After the myosin head detaches, energy from ATP hydrolysis is used to re-cock the myosin head.
What is the phase of the cardiac cycle that is caused by the sliding of actin and myosin?
Systole
How many pgal molecules can there be during the Calvin cycle?
There can be up to 12 PGAL molecules during the Calvin cycle

What effect would BMD have on the cross bridge cycle?
Myosin heads would remain detached, unable to cock.
What acts as ATPase during the contraction cycle of muscle?
myosin cross-bridges

At what stage in the cross-bridge cycle is ATP split into ADP and Pi?
Before the cross bridges of myosin can attach to actin.
How The Calvin Cycle Is A Bridge Carbon In The Atmosphere And Carbon Based Molecules In The Food You Eat?
The Calvin cycle is a carbon dioxide gas from the atmosphere and the energy carried by ATP and NADPH to make simple sugars.

Where are the cycle shelters at London Bridge station?
The cycle shelters at London Bridge station can be found at the corners. You are able to store your cycle there if you need to board a train to get to your desination.
