Answer: q#1 The phosphate tail of ATP is the actual power source which the cell taps.
q#2 atp
Explanation:
Nucleotides are the monomers of DNA. They consist of five-carbon sugar deoxyribose, a phosphate group and a nitrogenous base attached to the sugar. Nucleotides including adenine A thymine T guanine G and cytosine C are available.
DNA monomers or nucleotides can bind phosphates and sugars on the outside and nitrogenous bases on the inside where they can bind to other nitrogenous bases to form a ladder. DNA is a polymer. The monomeric units of DNA are nucleotides and the polymers are known as polynucleotides.
Monomers are small mostly organic molecules that can combine with other similar molecules to form very large molecules or polymers. All monomers have the ability to form chemical bonds with at least two other monomer molecules. The unique structure of DNA allows the molecule to replicate itself during cell division. When a cell prepares to divide, the DNA helix splits in the middle and becomes two single strands.

Following Statements Accurately describe the electron transport chain (ETC)
- Proton transport from the matrix to the intermembrane space is connected with electron transfer in the electron transport chain (ETC).
- Prosthetic groups, like iron-sulfur centers, are directly engaged in the transport of electrons.
- Small molecules and hydrogen ions can easily pass through mitochondria's outer membrane.
- Four complexes of proteins and prosthetic groups make up electron carriers.
- Ubiquinone (coenzyme Q) and cytochrome c are electron carriers in the electron transport chain (ETC).
The oxidative phosphorylation process, also known as the electron transport chain (ETC), is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP. Both photosynthesis and cellular respiration take place in mitochondria.
