Given:
Time: 3.5 hrs
Velocity: 120 miles/hour
Now Distance= Speed x Time
Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction.
Hence Distance= Velocity x Time
Distance= 3.5x20=420 miles

If no ATP is present in the muscle cell what would be the likely result?
Elden [556K]

Answer: c. The myosin would not be able to let go of the actin

Explanation:

Muscles consists of two proteins called actin and myosin and responsible for muscle contraction.

Myosin is ATP dependant and when ATP binds to it, it is able to release the actin.

This will allow the actin and myosin to seperate from each other thus leading to muscle contraction
