DCCC BIO150 LECTURE TEST #4 QUESTIONS
WITH CORRECT ANSWERS 2026
Energy - CORRECT ANSWER -the ability to do work
Chemical energy - CORRECT ANSWER -potential energy stored in chemical bonds
Work - CORRECT ANSWER -force exerted on an object that causes it to move
Kinetic energy - CORRECT ANSWER -energy of motion
Potential energy - CORRECT ANSWER -stored energy
ATP - CORRECT ANSWER -energy
Structure of ATP - CORRECT ANSWER -adenine, ribose, 3 phosphate groups
Energy in ATP is stored in - CORRECT ANSWER -bond between the last two phosphates
ATP hydrolysis - CORRECT ANSWER -ATP and water is converted to ADP, inorganic phosphate,
and energy
ATP synthesis - CORRECT ANSWER -transferring of energy from the chemical bonds of nutrients
to the phosphate bonds of ATP, ADP+P=ATP
Phosphorylation - CORRECT ANSWER -the transfer of a phosphate group, usually from ATP, to a
molecule
, Purpose of phosphorylation - CORRECT ANSWER -regulate protein function and cellular
signaling by altering the protein's structure and activity, essentially acting as a "switch" to turn
processes on or off within the cell; this is considered a key way to control various cellular
processes like cell cycle, metabolism, and signal transduction pathways
Cellular respiration - CORRECT ANSWER -chemical breakdown of glucose to form ATP
3 separate reactions in cellular respiration - CORRECT ANSWER -1. Glycolysis
2. Krebs cycle
Electron transport chain
Aerobic respiration - CORRECT ANSWER -requires oxygen
Anaerobic cellular respiration - CORRECT ANSWER -the process by which cells obtain energy
from an energy source without using oxygen
Glycolysis equation - CORRECT ANSWER -glucose --> pyruvic acid + 2ATP
Pyruvic acid - CORRECT ANSWER -converts to lactic acid and too much inside muscle cells will
cause muscle cramps
Myology - CORRECT ANSWER -study of muscles
Functions of the muscular system - CORRECT ANSWER -1. Movement of the body
2. Stabilize posture
3. Heat production
