Biology End of Course (EOC) Exam CP Preparation
Background: You will work on these questions all week in preparation for the NJ Biology EOC Exam next week. I will intermittently provide overviews of each topic during class. Your success on this exam is particularly important for our district and your teachers (me J) as a guide for where we are succeeding or failing in our preparations for this exam. The exam’s designers will also carefully evaluate responses to each question, making final revisions in preparation for next year’s version. Next year, for the first time, Biology students will have to pass the EOC exam as a graduation requirement like the HSPA. You will not have to take it. However, your efforts now are key to creating a valid and fair exam.
Our early assessment of the Biology EOC Exam is that there is an emphasis on scientific thinking, experimentation, and interpretation of results. Understanding the inputs and outcomes of processes and understanding their implications is more important than memorizing part and process names.
Assignment = 25 points. Ch. 1-6= 10 pts; Ch. 7-11= 10 pts; Ch. 12-17=5 pts.
Chapter 1 Biology Applications
#1) Use all steps of the Scientific Method for the following scenario:
Researchers observed that a restriction enzyme they made (PHS010) cuts a gene in the DNA of Influenza virus strain JNGP1.
Influenza viruses cause respiratory flu, with symptoms including high fever.
The team questions if patients with this enzyme would have reduced fever.
(Patients could receive a gene for this enzyme via a viral vector delivered to the lungs with an inhaler (Gene Therapy).
Use the Scientific Method to outline how you would proceed. Identify Independent and Dependent variables, and describe how you’d set up a Control Group.

What’s the Life of a Cell Like? A Biology EOC Exam Review
Bottom line: Cells carry out chemical reactions [Metabolism]. These reactions include making and breaking molecules.
Making molecules includes:
· Photosynthesis makes glucose (C6H12O6) from CO2 and H2O (sunlight provides energy to make this reaction happen.
· Cellular Respiration makes ATP (Adenosine Triphosphate) from ADP (Adenosine Diphosphate) and a free phosphate. ATP provides the perfect amount of energy for nearly all reactions in cells (making, moving and breaking molecules)
· Making proteins (protein synthesis) following instructions in DNA to bond together amino acids to build proteins on ribosomes, helped by endoplasmic reliculum and golgi.
· DNA replication from nucleotides.
· Make new membranes for new cells and organelles using fatty acids and phosphate groups to make phospholipids.
Breaking Molecules includes:
· Cellular Respiration breaks bonds in glucose to supply energy to recharge ADP into ATP
· Digestion and cell lysosomes use enzymes to digest nutrients and other molecules.
· Proteins à Amino Acids
· Complex carbohydrates (polysaccharides) like starch and glycogen for energy storage à simple carbs (monosaccharides) like glucose, needed by mitochondria.
· Fats and oils (lipids) à fatty acids
· DNA & RNA à nucleotides.
A lot of this making and breaking of molecules is to maintain homeostasis, to keep normal constant conditions inside the cell.
This involves using membrane proteins to regulate what goes in and out of the cell.
· Ex. when glucose concentration is lower inside cell than outside, glucose will diffuse in until equilibrium is reached.
· Ex. Sodium can be actively pumped out of a cell
· Ex. Large proteins, like neurotransmitters or enzymes, can be transported out of a cell in a vesicle (exocytosis)
Cells respond to their surroundings. For example, a signal protein made and released by one cell (ex. motor neuron) can trigger a receptor protein in another cell (ex. muscle cell), causing it to respond (ex. muscle protein contraction).
Growth can involve one cell taking in more nutrients to build more organelles, etc, or it can involve cell division to make more cells. Before a cell divides, the DNA must be replicated to make two sets (one for each resulting cell) [Synthesis phase]. Each of these identical chromatids is paired into a coiled chromosome. The process of dividing the replicated DNA into two new nuclei is called mitosis. After mitosis, the rest of the cell must be divided to make the two new identical cells (cytokinesis).
To reproduce, cells divide. However, eukaryotic organisms, with a nucleus in their cells, reproduce sexually. They divide germ cells a second time (meiosis) to create haploid gametes. Each gamete can pass on the genes from that parent (heredity). Since populations struggle to survive in a changing environment, nature selects traits that aid survival, leading to gradual evolution over many generations.
