• A) \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\ \cos t = - \frac { 4 } { 5 } \\ \tan t = - \frac { 3 } { 4 } \end{array}\)
• B) \(\begin{array} { l } \sin t = \frac { 3 } { 5 } \\ \cos t = - \frac { 3 } { 4 } \\ \tan t = \frac { 4 } { 5 } \end{array}\)
• C) \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\ \cos t = - \frac { 3 } { 4 } \\ \tan t = \frac { 4 } { 5 } \end{array}\)
• D) \(\begin{array} { l } \sin t = \frac { 3 } { 4 } \\ \cos t = \frac { 3 } { 5 } \\ \tan t = \frac { 4 } { 5 } \end{array}\)
• E) \(\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\ \cos t = - \frac { 4 } { 5 } \\ \tan t = \frac { 3 } { 4 } \end{array}\)

Definitions:

Catabolized

The process by which substances are broken down into smaller molecules to release energy.

Ketogenesis

A metabolic process where the liver produces ketone bodies from fatty acids, which serve as an alternative energy source when glucose is low.

Acetyl CoA

A molecule involved in many biochemical reactions, serving as a key intermediary in the synthesis and oxidation of fatty acids and in the Krebs cycle for energy production.

Electron Transport

A series of chemical reactions during which electrons are transferred through a chain of protein complexes in the mitochondria, generating ATP, the cell's energy currency.
