Term
Define Adenosine Triphosphate
Definition

ATP; 

The molecule that delivers usable chemical energy for almost all processes and reactions that a cell must undergo to survive.

Term
Define DNA
Definition

Deoxyribonucleic Acid;

this is the molecule, unique to each individual, carrying the genetic information to be found in every cell; all the information an organism needs to live and reproduce is contained in its DNA.

Term
Define Enzyme
Definition
A protein that is a catalyst for chemical reactions in organisms; it increases the rate of the reacton without being used up or changed
Term
Define Gene
Definition
A segment of DNA that directs the development of some inherited traits.
Term
Define Protiens
Definition
One of the four major classes of large molecules, made of amino acids.
Term
Define RNA
Definition
Ribonucleic Acid; nucleic acid that uses the instructions stored in DNA to build proteins.
Term
Define Transcription
Definition
The synthesis of an RNA molecule using a DNA molecule for a template.
Term
Define Translation
Definition
The process in which proteins are produced based on instructions carried by mRNA.
Term

True or False

Genes are directions for building proteins.

Definition
True
Term
We think of DNA as......
Definition
The Blueprint
Term
RNA uses DNA to build what?
Definition
Proteins
Term
Where is RNA made?
Definition
The DNA makes RNA in the nucleus.
Term
Is RNA a copy of every DNA segment? Or only a few?
Definition

RNA is  a copy of certain DNA segments.

 

Term
The process of making RNA from DNA is called...
Definition
Transcription.
Term
How are RNA molecules transcribed from DNA codes and translated into 3D proteins structures?
Definition

1. Transcription - DNA makes RNA in the nucleus.

 

2. Translated - RNA carries the code it has transcribed from DNA to ribosomes in the cytoplasm to build either a single protein or a part of protein in a process called translation.

Term
What is a polyeptide?
Definition
part of a protein.
Term
Proteins are made out of various combinations of...
Definition
Polypeptides.
Term
How many proteins does the human body produce?
Definition
100,000
Term
Most activities in and out of the cells are carried out by actions of.....
Definition
proteins.
Term
Proteins are like what in a big company?
Definition
Workers
Term
Can proteins be organized into groups? If yes, expain.
Definition
Yes; based on the jobs they have or do.
Term
As energy is used, what happens to ATP?
Definition
ATP changes into ADP
Term
What enzyme is used for the conversion of ATP to ADP?
Definition
ATPase
Term
Usually enzymes end in what ending?
Definition
"ase"
Term
What do enzymes do?
Definition
speeds up reactions in living things.
Term
can Proteins be enzymes?
Definition
Yes
Term

Hormone that is unvoled in the regulation of sleep, mood, and appetite.
Term

True Or False

 

All proteins work inside the cell only.

Definition

False.

 

Some proteins work inside and outside of the cell.
