Unit 1: The Chemistry of Life
These are the monomers of nucleic acids, such as DNA and RNA.
What are nucleotides?
Molecules only diffuse through the semipermeable membrane of the cell if they have these two properties.
What are small and nonpolar?
What is the activation energy?
Any molecule (hormone, chemical messenger, signal, etc.) that binds to a receptor protein may be called this.
What is a ligand?
What are Hydrogen Bonds?
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?
The Krebs cycle (citric acid cycle) takes place here.
Mitochondrial matrix
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?
Polymers are broken apart using this this process, which involves the addition of water to break the covalent bonds.
What is hydrolysis?
This is the correct sequence of the transport of proteins.
RER--> Golgi --> Vesicles -->Plasma membrane
These are the two main processes of photosynthesis.
What are the light dependent reactions and the Calvin cycle.
Cells typically enter mitosis to complete one of these functions.
Growth and cell repair.
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?
Lysosomes play a role in intracellular digestion as well as well as apoptosis due to their containing these.
What are hydrolytic enzymes?
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?
Stage of the cell cycle in which cells spend most of their time.
What is interphase?
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?
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?
ATP and NADPH
What are the products of the light reactions that are needed for the Calvin cycle.
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?
