• Golgi to ER to lysosome
• nucleus to ER to golgi
• ER to Golgi to secretory vesicles
• ER to lysosomes to vesicles

What 4 structures are common between plant, animal, and bacterial cells?

• Golgi Apparatus, Chloroplasts, Ribosomes, Nucleus
• Cell Wall, Mitochondria, Cell Membrane, Cytoplasm
• Rough ER, Smooth ER, Nucleus, Ribosomes
• DNA, Cytoplasm, Ribosomes, Cell membrane

Which would decrease the entropy?

• dehydration reaction
• hydrolysis reaction
• exothermic reaction
• digestion

What is free energy?

• total energy in a system
• extra energy emitted by a system
• energy available to do work
• the same as entropy

Moving free energy from a catabolic reaction to fuel an anabolic reaction is accomplished through -

• feedback regulation
• bioenergetics
• energy coupling
• entropy

This reaction shows a(n) ____________ reaction

• Catabolic
• Anabolic
• Dehydration Synthesis
• Halogenation

The area that the substrate fits into on the enzyme is called the:

• Active Site
• Allosteric Site
• DiSulphide Bridge
• β-Pleated Sheet

Enzymes catalyze reactions by ___________ Activation Energy.

• Increasing
• Decreasing

At high temperatures enzyme activity declines because of:

• Denaturation
• Decreased Kinetic Motion
• Increased H-Bonding
• Dissociation of Ionic Compounds

The molecule an enzyme is working on is called the:

• Substrate
• Solvent
• Allosteric Inhibitor
• CoEnzyme
