Concept 1: Enzymes
A reaction that releases more energy than it absorbs.
Exothermic
Macromolecule first to be broken down into ATP.
Carbohydrates
Chemists are measuring the length of time it takes for different amounts of antacid to neutralize stomach acid. Different amounts of antacid is call the _______ variable.
Independent
Organelle that converts light energy into chemical energy stored in sugar.
Chloroplast
Specific phase of the cell cycle where DNA is replicated.
S phase (of interphase)
The substance(s)listed to the right of the arrow in a chemical equation. X + Y ---> XY
Products
ATP releases energy when a ___________ is removed.
Phosphate
Chemists are measuring the length of time it takes for different amounts of antacid to neutralize stomach acid. Length of time to neutralize is call the _______ variable.
Dependent
Organelle that makes proteins.
Ribosome
A signal from a cell's own DNA would be considered _____ regulation, whereas a signal from a hormone in a person's body would be considered _______ regulation.
internal,external
If the activation energy of a biochemical reaction is lowered, then the reaction will happen _________.
Faster
Where your body receives the energy stored within ATP.
Food - usually from carbs!
Macromolecule that makes up enzymes
protein
Solution that has more solute than a cell causing the cell to shrink.
Hypertonic
Stages of Interphase
G1, S, and G2
The molecule that binds to an enzyme.
Substrate or reactant
The three parts of an ATP molecule.
Adenine, ribose, 3 phosphates
6 elements essential to life
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulfur
Specific process that uses energy to bring something in from outside the cell.
Endocytosis
Phases of Mitosis
Prophase, Metaphase, Anaphase, Telophase
Active site
ATP is formed and energy is stored when a phosphate joins this molecule.
ADP
Molecule with an unequal distribution of charges, such as water.
Polar
Organelle known as the powerhouse of the cell.
Mitochondria
During plant cytokinesis a ________ forms between the two cells, where as in animal cytokinesis a _______ forms.
cell plate, cleavage furrow.
