ADP Pi are a set of molecules that store energy for catabolism. Pi acts as a shuttle molecule to move energy from ATP to ADP. Energy from catabolism can be used directly for performing cellular work. ATP is a molecule that acts as an intermediary to store chemical energy for cellular work. True or false?

True

Explanation:

Adenosine triphosphate also known as ATP is a biological complex molecule that function as an energy carrier for storing and transferring energy. Therefore, it is also known as molecular unit of currency.

Energy released from catabolism stores in ATP in the form of phosphate bond.  

Energy released when a phosphate bond is broken. ATP releases energy and convert to ADP and AMP. So, it also acts as an intermediary to store chemical energy for cellular work.

Therefore, the given statement is true.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
