100

These are the monomers of nucleic acids, such as DNA and RNA.

What are nucleotides?

100

Molecules only diffuse through the semipermeable membrane of the cell if they have these two properties.

What are small and nonpolar?

100
Enzymes function in cellular reactions by lowering this. 

What is the activation energy?

100

Any molecule (hormone, chemical messenger, signal, etc.) that binds to a receptor protein may be called this.

What is a ligand?

200
Many of the properties of water (adhesion, cohesion, surface tension, high specific heat, etc.) are a result by its ability to form these with each other.

What are Hydrogen Bonds?

200

In order for cells to efficiently exchange materials with their surrounding, they contain highly folded membranes that increase this in the cell.

What are surface area to volume ratios?

200

The Krebs cycle (citric acid cycle) takes place here.

Mitochondrial matrix

200

The S phase of the cell cycle is responsible for doubling the amount of DNA in a cell, while the M phase is responsible for doing this to it.

What is cutting it in half?

300

Polymers are broken apart using this this process, which involves the addition of water to break the covalent bonds.

What is hydrolysis?

300

This is the correct sequence of the transport of proteins.

RER--> Golgi --> Vesicles -->Plasma membrane

300

These are the two main processes of photosynthesis.

What are the light dependent reactions and the Calvin cycle.

300

Cells typically enter mitosis to complete one of these functions.

Growth and cell repair.

400

Altering the pH, temperature or salinity of an enzyme may change its structure and in turn its function due to the differences in the characteristics and interactions of these. 

What are the R groups?

400

Lysosomes play a role in intracellular digestion as well as well as apoptosis due to their containing these.

What are hydrolytic enzymes?

400

The functioning of ATP synthase in the inner membrane of the mitochondria is determined by the generation of an H+ concentration gradient. A gradient that is generated by this.

What is the electron transport chain?

400

Stage of the cell cycle in which cells spend most of their time.

What is interphase?

500

Lipids differ from the other 3 classes of macromolecules in that they have this property, such as in the tails of phospholipids. 

What is nonpolar?

500

The rough and smooth ER are similarly folded membranes. The rough ER is studded with ribosomes for protein synthesis, while the smooth ER's function is to detoxify and synthesize these.

What are lipids?

500

ATP and NADPH

What are the products of the light reactions that are needed for the Calvin cycle.

500

Cancer cells may proliferate uncontrollably and form tumors due to the fact that they do not respond to apoptotic signals or density-dependent factors. They may also divide uncontrollably because they proceed through the cell cycle even in the absence of these.

What are growth factors?
