The correct answer is: " enzymes " .

______________________________________________

Note that "enzymes" are "biological catalysts" .

______________________________________________

"Catalysts" are agents that 'increase the rate of' , or 'speed up' , a 'chemical reaction' , when added to the reactants; and by definition, catalysts do so within affecting the reaction itself.

As aforementioned, "enzymes" can function as "biological catalysts" — which means that enzymes within the cell membrane can 'speed up' , or 'increase the rate of' , biological reactions (i.e. biochemical reactions) — without affecting the biological reaction (i.e. biochemical reaction) itself.

What accounts for the ability of vesicles to fuse with different membrane compartments in the cell?

aalyn [17]

<span>The phospholipid bilayer has a fluid makeup, so this allows vesicles to go from one part of the cell to another and fuse with those areas. The vesicles then go into these areas and deposit the needed substances or pick up waste products from these areas in order to remove them from the cell.</span>

Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it complet

mina [271]

Answer:

5.7 m/s

Explanation:

The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:

1) The Physical principle: conservation of momentum.

If there is no net external force operating on a system, so the system's total momentum is conserved

The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:

P = mv.

2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.

Based on this, the calculation is as follows

Momentum before the collision:

$P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity$
