Assembled from 20 different types of these.

Answer…

What are amino acids?

Any substance bound by a protein is referred to as this.

Answer…

What is a ligand?

Level of organization that includes the alpha-helix and beta-sheet within the polypeptide chain.

Answer…

What is the secondary structure?

Pictured here are different types of this kind of bond, which is also the majority of bonds seen in proteins.

Answer…

What are non-covalent bonds?

These give proteins their unique properties.

Answer…

What are amino acid side chains?

This is the conversion of one type of signal to another.

Answer…

What is signal transduction?

Communication this way is a long range (whole body) due to a chemical signal, such as hormones.

Answer…

What is an endocrine?

Location of this is determined by the nature of the ligand. (i.e. intracellular vs. surface)

Answer…

What is a receptor?

These two enzymes act as molecular switches by adding or removing phosphate groups.

Answer…

What is a kinase and phospatase?

Pictured here is one of the ‘between cell’ signaling.

Answer…

What is contact-dependent signaling?

Energy is never created or ____.

Answer…

What is destroyed?

The Citric Acid Cycle is also known as this.

Answer…

What is the Krebs Cycle?

During the digestion of the granola bar you had for breakfast, this stage of breakdown will generate the most ATP.

Answer…

What is Oxidative Phosphorylation?

Direct burning of sugar instead of stepwise oxidation results in this loss.

Answer…

What is loss of free energy by heat?

During fermentation an important reaction occurs producing NAD+ from this.

Answer…

What is NADH?

During cell division a parent cell will divide into these.

Answer…

What are two daughter cells?

Parent

Daughter

Chromosomes are duplicated and aligned at the equator plane during this phase.

Answer…

What is Metaphase?

During this stage cleavage of the cytoplasm into two daughter cells occurs.

Answer…

What is cytokinesis?

The arrow points to this named indentation to begin the cleavage process.

Answer…

What is the cleavage furrow?

This is the protein complex surrounding the centromere.

Answer…

What is a kinetochore?

Outer membrane that controls the traffic in and out of the cell.

Answer…

What is the Plasma Membrane?

Pictured here, I contain your genetic DNA!

Answer…

What are Chromosomes?

These organelles produce a lot of proteins , with a lot of these within a cell.

Answer…

What are Ribosomes?

Without me you would not have any way to produce energy in your body.

Answer…

What is the Mitochondria?

Organelle that contains a Rough and Smooth part to it.

Answer…

What is the Endoplasmic Reticulum?
