BIOD 151 Module 1 Questions And Answers Verified A person standing in anatomical position moves their right wrist laterally toward the radius - what is this action called? - Radial deviation A transverse plane divides the body into these two parts. - superior and inferior active transport - When molecules or ions are pumped from an area of lower concentration to an area of higher concentration. This requires extra energy and carrier proteins because the molecules are going against the concentration gradient. Away from the body surface is what direction? - Deep Away from the head end or toward the lower part of a structure of the body is what direction? - Inferior Between a more medial and a more lateral structure is what direction? - Intermediate cholesterol - Cholesterol is a lipid that is very hydrophobic and has one polar hydroxyl group. It joins with phopholipids and mixes in with the tails to prevent solidification during low temperatures. It also stabilizes the phospholipd head with the hydroxyl group by restricting movement in higher temperatures. Closing of a joint is which action? - Flexion Define depression in anatomy - downward movement of a structure Define elevation - upward movement of a structure Define protraction - the movement of a structure in the anterior direction Define retraction - the movement of a structure in the posterior direction Describe aerobic respiration and the purpose of ATP production - ATP provides energy to cells. Aerobic respiration is the process in which oxygen is used to break down food and convert the chemical energy in it into ATP. diffusion - Diffusion is when molecules move from an area of higher concentration to an area of lower concentration to achieve equilibrium with the two sides of a membrane. (small molecules such as gases, water, and glycerol as well as lipid-soluble molecules such as hydrocarbons) Facilitated diffusion is used for a lipid-insoluble
