9th Grade Honors Biology – ATP With
Questions And Answers
active transport - Answer - drives molecules across a membrane from a region of lower concentration to
a region of higher concentration, uses transport proteins powered by chemical energy
endocytosis - Answer - the process of taking liquids or fairly large molecules into a cell by engulfing
them in a membrane
phagocytosis - Answer - a type of endocytosis in which the cell membrane engulfs large particles (cell
eating)
exocytosis - Answer - the release of substances out of a cell by the fusion of a vesicle with the
membrane
ATP - Answer - a molecule that transfers energy from the breakdown of food molecules to cell
processes
ADP - Answer - a lower-energy molecule that can be converted into ATP by the addition of a phosphate
group
chemosynthesis - Answer - a process by which some organisms use chemical energy instead of light
energy to make energy-storing carbon-based molecules
cellular respiration - Answer - releases chemical energy from sugars and other carbon-based molecules
to make ATP when oxygen is present
aerobic - Answer - needs oxygen to take place
, glycolysis - Answer - splits glucose into two three-carbon molecules and makes two molecules of ATP
anaerobic - Answer - does not need oxygen to take place
Krebs cycle - Answer - produces molecules that carry energy to the second part of cellular respiration,
takes place in the interior space, or matrix, of the mitochondrion
chemical reactions - Answer - change substances into different substances by breaking and forming
chemical bonds
reactants - Answer - the substances changed during a chemical reaction
products - Answer - the substances made by a chemical reaction
enzyme - Answer - a substance produced by a living organism which acts as a catalyst to bring about a
specific biochemical reaction, also a type of protein, but not all proteins are enzymes
citric acid - Answer - a six-carbon compound formed in the Krebs cycle
C₆H₈O₇
pyruvate - Answer - Three-carbon compound that forms as an end product of glycolysis
C₃H₄O₃
ATP is introduced as an energy currency. What does ATP stand for? - Answer - adenosine triphosphate
Which type of biomolecule is ATP? Recall the biomolecules include carbohydrates, lipids, proteins, and
nucleic acids. - Answer - Nucleic acid
As a nucleotide derivative, ATP has three major components. Label the following parts of ATP. - Answer
- 1. Base (adenine)
