water molecule is used
When a sucrose molecule is decomposed to yield a glucose molecule and a fructose molecule
lose H2O to form bonds; use H2O to break bonds
Dehydration synthesis reactions _____, whereas hydrolysis reactions _____
a molecule, usually a protein, that speeds the rate of a biochemical reaction by lowering the activation energy
The basic steps of an enzyme-catalyzed reaction are
substrate and enzyme combine, forming an E-S complex. The reaction occurs, products are released, and the unchanged enzyme is released and recycled
an enzyme and its substrate
interaction between_____ _____ is when part of the enzyme temporarily binds part of the substrate molecule
An important mechanism that controls metabolic pathways under physiological conditions
number of enzyme molecules, number of substrate molecules, and efficiency of the enzyme
Three factors that increase the rates of enzyme-controlled reactions
enzymes; copper, iron, and zinc
A cofactor is a necessary part of some ______ and examples are _____.
it provides energy for cellular work when the terminal, high-energy bond is broken
ATP is important to cellular processes because
ATP molecules in living cells
hold energy from the oxidation of fuels in their high-energy phosphate bonds, and the energy is used in various cell processes
uses enzymes to lower the activation energy
Oxidation during cellular respiration differs from burning in that respiration
Acetyl Coenzyme A
A molecule that is common to carbohydrate and lipid metabolic pathways and connects these two pathways metabolically
cytoplasm without O2 required; mitochondria with O2 required
Anaerobic respiration occurs in _____, whereas aerobic respiration occurs in ______
If one strand of DNA has the sequence TCAGGCTATTCCCG, then the complementary sequence of the other strand is
during ____ _____ the DNA double helix comes apart where hydrogen bonds join base pairs, and new nucleotides are brought in, forming two double helices
transcription produces RNA and translation produces protein
Transcription and translation differ in that
a change in a DNA sequence in less than 1% of a population that affects anatomy and/or physiology
A mutation can cause disease if
the DNA sequence changes so that one amino acid is substituted for another in a way that affects the encoded protein's functioning
The electron transport chain is a series of enzyme complexes that pass electrons, releasing energy that is used to phosphorylate ADP to ATP on the inner mitochondrial membrane
During anaerobic conditions, when low oxygen levels may occur, glucose is converted to what stable end product to provide ATP energy
The formation of ATP involving the loss of hydrogen atoms and the bonding of phosphate to ADP
During the process of protein synthesis, amino acids are positioned in proper sequence by molecules of
The leading strand is replicated continuously, while the lagging strand is replicated discontinuously
