In a cell, information that controls the production of proteins must pass from the nucleus to the 
(1)	Cell Membrane	    (3) Mitochondria
(2)	Chloroplasts       (4) Ribosomes

When organisms break the bonds of organic compounds, the organisms can

(1) use the smaller molecules to plug the gaps in the cell membrane to slow diffusion
(2) use the energy obtained to digest molecules produced by respiration that uses oxygen
(3) obtain energy or reassemble the resulting materials to form different compounds
(4) excrete smaller amounts of solid waste materials during vigorous exercise

Two proteins in the same cell perform different functions. This is because the two proteins are composed of

(1) chains folded the same way and the same sequence of simple sugars
(2) chains folded the same way and the same sequence of amino acids
(3) chains folded differently and a different sequence of simple sugars
(4) chains folded differently and a different sequence of amino acids

Which part of a molecule provides energy for life
processes?

(1) carbon atoms         (2) oxygen atoms           3) chemical bonds       4) inorganic nitrogen

Three days after an organism eats some meat, many of the organic molecules originally contained in the meat would be found in newly formed molecules of

(1) glucose  (2) protein         (3) starch         (4) oxygen

The diagram below represents the synthesis of a portion of a complex molecule in an organism.

Which row in the chart could be used to identify the building blocks and product in the diagram?
 Row  	Building Blocks      	Product 	
 (1)	 starch molecules
	glucose 	
 (2)	 amino acid molecules
	part of protein 	
 (3)	 sugar molecules
	ATP 	
 (4)	 DNA molecules               
	part of starch

The diagram below represents two molecules that can interact with each other to cause a biochemical process to occur in a cell.

Molecules A and B most likely represent
(1) a protein and a chromosome
(2) a receptor and a hormone
(3) a carbohydrate and an amino acid
(4) an antibody and a hormone
