Two Nonparallel Vectors Determine a Plane

question 21

Multiple Choice

Two nonparallel vectors determine a plane. Relative to the plane determined by the position vector and velocity vector of a particle, in which direction is the angular momentum vector about the origin?

• A)in the plane, but perpendicular to the velocity vector
• B)in a direction dependent on the magnitudes of the velocity and position vectors
• C)perpendicular to the plane
• D)in the plane, but perpendicular to both the position vector and the velocity vector
• E)in the plane, but perpendicular to the position vector

Electron Transport

is a series of chemical reactions that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

Oxygen

Oxygen is a chemical element with symbol O and atomic number 8, essential for the respiration of most living organisms and for combustion processes.

Acetyl CoA

is an important molecule in metabolism, acting as a substrate for the citric acid cycle in energy production and synthesis of fatty acids.

Citric Acid Cycle

All aerobic life forms use this collection of chemical processes to create energy, transforming acetate sourced from carbs, fats, and proteins into carbon dioxide.
