When water freezes, it forms a lattice crystal, causing ice to float. Large bodies of water stabilize climates due to water's high specific heat. The polarity of water's bonds allows for covalent bonding between molecules. Hydrogen bonding results in water having strong cohesive and adhesive properties. ️The polarity of water's bonds allows for covalent bonding between molecules. Which biologic molecule would you recommend a patient limit if they want to avoid having cardiovascular problems? Unsaturated fats Carbohydrates Phospholipids Saturated fats ️Saturated fats DNA and RNA are subunits of which type of biologic molecule? Proteins Lipids Nucleic acids Carbohydrates ️Nucleic acids Which type of protein acts to catalyze different reactions or processes? Amino acids Enzymes Steroids Hormones ️Enzymes What are the three types of lipids? Fatty acids, enzymes, and steroids Fatty acids, phospholipids, and enzymes Fatty acids, saturated fats, and unsaturated fats Fatty acids, phospholipids, and steroids ️Fatty acids, phospholipids, and steroids In a cell, reactions take place in a series of steps called ____________? catabolic pathways metabolic pathways the electron transport chain cellular respiration ️metabolic pathways What function do cholesterol molecules serve within the cell membrane? They allow for carbohydrate chains to extend beyond the cell membrane to communicate with other cells. They allow the cell membrane to be selectively permeable by making the bilayer structure more flexible. They act as transport highways for molecular movement into and out of the cell. They stabilize the flexible bilayer structure to prevent breakage. ️They stabilize the flexible bilayer structure to prevent breakage. Although animal cells lack cell walls, they do have an elaborate system of glycoproteins that provide support to the outside of the cell called the: extracellular matrix endomembrane system cytosol cytoskeleton ️extracellular matrix If an animal cell is left in an unknown solution overnight, and the next day the cell bursts, it can be assumed that the unknown solution is: hypotonic hypertonic isotonic tonic ️hypotonic Which organelle is responsible for storing, modifying and sending out products of the endoplasmic reticulum, such as proteins? Endoplasmic reticulum Ribosomes Golgi apparatus Lysosomes ️Golgi apparatus Which cell organelle functions in the detoxification and metabolism of multiple molecules? Lysosomes Smooth endoplasmic reticulum Golgi apparatus Rough endoplasmic reticulum ️Smooth endoplasmic reticulum A flagellum is a whip-like appendage found on the surface of some cells. What is their primary purpose? Membrane production Transport proteins throughout the cell Detoxification of medications and poisons Movement of the cell ️Movement of the cell Which type of cell lacks a defined nucleus? Animal cell Eukaryotic cell Plant cell Prokaryotic cell ️Prokaryotic cell Which step in cellular respiration takes place in the mitochondria of the cell and produces two ATP molecules, six carbon dioxide molecules, and six NADH molecules for every molecule of glucose? The Calvin cycle Electron transport chain The Krebs cycle Glycolysis ️The Krebs cycle Which of the following statements about catabolic pathways that lead to cellular respiration is correc
