Answer:
A
Explanation:
The structure of ATP is such that there are three (3) phosphate moelcules in sequence attached to the 5’ carbon of the ribose sugar ring. The O- groups of each phosphate are close to each other and are negatively charged. They, therefore, repel each ohtehr electrostatically and make ATP very unstable – hence considered weak bonds. ADP is more stable than ATP. Nonetheless, phosphoanhydride bonds between the phosphate have high energy of ΔG of -30.5 kJ/mol. These characteristic make ATP ideal as ane energy currency since it is easy to hydrolyze while producing much energy.
Answer:
Polygenic.
Explanation:
A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes".
Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkali metals.
Answer:
The skin
Explanation:
because it protects the internal organs just like the cellwall of the cell
Answer:
- All of the following are correct
- Muscle cells are surrounded by a branching network of transverse tubules.
Explanation:
Muscle cells are composed of myofibrils, which are the fundamental and functional parts of a muscle cell. Myofibrils are the ones that are surrounded by a branching network of transverse tubules. These transverse tubules are extensions of the sarcolemma or the muscle cell's membrane. Their distribution and connection to myofibrils allow for the passage of Calcium ions needed for contraction.
