Question

name:
biol 105 exam 2

1. atp breakdown in cells is accompanied by:

a. phosphate bonding.
b. a release of energy.
c. an endergonic reaction.
d. energy storage.

1. atp is a type of ____, and share similar chemical structure to dna and rna.

a. protein
b. nucleic acid
c. lipid
d. amino acid

Explanation:

For question 49, when ATP breaks down in cells, the high - energy phosphate bonds are cleaved, releasing energy. An endergonic reaction requires energy input, and ATP breakdown is an exergonic process. Energy storage is not what occurs during ATP breakdown. Phosphate bonding is not the main event during ATP breakdown.
For question 50, ATP (adenosine tri - phosphate) is a nucleotide derivative. Nucleic acids like DNA and RNA are made up of nucleotides. Proteins are made of amino acids, lipids have different chemical structures from ATP, and amino acids are the building blocks of proteins, not what ATP is classified as.

Answer:

1. B. a release of energy
2. B. nucleic acid
