Answer:
Bond D
Explanation:
The molecule in the model attached to this question is ADENOSINE TRIPHOSPHATE, commonly known as ATP. ATP is a unique molecule that carries and transfers energy in the cells of living organisms. It is made up of three components namely: ADENINE (nitrogenous base), RIBOSE (pentose sugar), PHOSPHATE GROUP (three).
ATP is able to carry out its function of storing and transferring energy via one of it's phosphate bonds (the last). ATP stores energy when a phosphate group is added to ADP to form ATP while it releases/transfers energy for use when that last phosphate bond is broken. Hence, according to this question, ATP releases the most energy for cellular processes when BOND D (last phosphoanhydride bond) is broken.
1. The tall, fair-skinned Vikings became known as brutal fighters and robbers.
a. True.
Calcium and phosphorus (as phosphate)
Answer:
Yes
Explanation:
In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed.
