ADP + P Glucose NAD Which of the following IS a capability of natural selection? Allows for the fittest individuals to produce more offspring. What does it mean when we say the genetic code is redundant? More than one codon can specify the addition of the same amino acid. What amino acid sequence will be generated, based on...

Honors Biology Unit 1 Study Guide Questions With Complete Solutions What role do proteins play in cellular processes? Proteins serve as enzymes, structural components, and signaling molecules, playing a key role in cellular functions. How does the structure of a phospholipid contribute to the formation of cell membranes? Phospholipids have hydrophilic heads and hydrophobic tails, forming a bilayer that creates a selective barrier for the cell. Why is the process of homeostasis cr...

Bio 1201 exam 2 Gregg latest update graded A+ transport proteins are responsible for controlling passage across the membrane fluid mosaic model The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails nonpolar, hydrophobic fatty acid heads hydrophilic, polar periphial proteins bound to the surface of the membrane integral proteins penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How ...

Dehydration Small molecules combine to form larger ones. For example: sugar monomers combine to form starch polymers Hydrolysis One larger molecule is split by the addition of H+ and OH- (from water) to the components Polymers large chains of identical molecular units strung together Monomers the units that serve as the building blocks of polymers Another name for a dehydration reaction is... condensation reaction Cells contain ___ major families of sma...

Describe the fluid-mosaic model of membrane structure. The framework of the membrane is the phospholipid bilayer, which consists of two layers of phospholipids. Also includes proteins and carbohydrates. Identify the three different types of membrane proteins. 1. Transmembrane Protein 2. Lipid-Anchored Protein 3. Peripheral Membrane Proteins Transmembrane Protein integral membrane protein that spans the entire width of a cell membrane Lipid-Anchored Proteins covalent attachment of a lipid to a...

Disaccharide A double sugar, consisting of two monosaccharides joined by dehydration synthesis. Glycosidic Linkage A covalent bond formed between two monosaccharides by a dehydration reaction. Phospholipid A lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar, hydrophobic tails, while the rest of the molecule acts as a polar, hydrophilic head. Phospholipids form bilayers that function as biological membranes....
