Welcome to A.P. Biology

Below are the instructions and schedule for the 2014 Review!

Unit 1 (biochemistry) fits under big idea 2: biological systems utilize free energy and molecular building blocks to grow, reproduce, and maintain dynamic homeostasis. To support this, here is a summary of a topic I had trouble with and reviewed from unit 1: functional groups. Functional groups are groups of elements responsible for reactions of compounds; side chains in proteins, proteins being made up of monomers amino acids, are examples of functional groups. Hydrophilic groups have oxygen and are polar, the others are no polar and hydrophobic. (If I posted this in the wrong spot, please tell me where to post it correctly here) thanks, Alex f.

Unit 2 (cells) fits under big idea 4: biological systems interact, and these systems and their interactions possess complex properties. To support this, here is a summary of a topic I had trouble with: cell communication.
Cells communicate in three ways, through connecting receptors to provide cell to cell contact, local regulators, and hormones. Receptors, like in macrophages and helper T cells, help with sending and receiving chemical messages over extremely short distances. Local regulators are chemical messages over less short distances and are specific, like the receptor communication. Hormones are general chemical messengers sent throughout the entire body, which do not always generate a response.

Unit 3 ( energy) fits under big idea 2: biological systems utilize free energy and molecular building blocks to grow, reproduce, and maintain dynamic homeostasis. To support this, here is a summary of a topic I had trouble with: cellular respiration. Cellular respiration takes place inside the mitochondria, and can be done with oxygen (aerobic) or without oxygen (anaerobic). It generates ATP, a significant source of energy for the cell, created after glucose (C6H12O6) and oxygen (6O2) are taken in and split into carbon dioxide (6CO2) and water (6 H2O). The three processes leading to this are glycolysis, breaking up glucose outside mitochondria, Krebs cycle, releases CO2 by converting acetyl CoA into various acids, then the electron transport chain, which accepts electrons from the Krebs cycle to make water with hydrogen ions and oxygen as the last acceptor in the electron transport chain. Lactic acid fermentation occurs in the absence of oxygen/mitochondria, it converts pyruvate into lactate to accept NADH electrons to recycle NAD+ so it can accept more electrons from
Glycolysis. Alcohol fermentation differs only by giving off carbon dioxide.

Unit 4 fits under big idea 3: living systems store, retrieve, transmit, and respond to information essential to life processes . To support this, here is a summary of a topic I had trouble with: difference between meiosis and mitosis. In meiosis, chromosomes come together and crossover mixing genetic information, then line up along the cell plate to be separated into two different cells. Another division occurs resulting in four cells with half the number of chromosomes. Mitosis is a single division leading to two identical cells with the same number of chromosomes.

Welcome to the 2013 - 2014 AP Biology Wiki !

What is a wiki?

A wiki is a website that can be edited by anyone. In this case, you and I will be the authors of this wiki!

Last year I used the WIKI to post links to helpful videos and other resources.The WIKI was also used by students to collaborate on several lab reports. They also created a Wiki for the purpose of review for the AP exam. This year we will be using it for a number of purposes.

  • First, there will be a page for each unit on which assignments will be posted. This page will also contain links to resources you might find helpful. This year, since all of you have iPads, I will be including links to PDF files for all assignments. These can be opened in Notability and completed on-line. Also, remember YOU are the co-authors of this WIKI so if you find a link, video or reference that you think your classmates would benefit from, please share it on the appropriate unit page.

  • Second, you will be collaborating with your lab partners to produce some of your final lab reports. These will be posted on the WIKI. You will also complete some collaborative research projects using the WIKI.

  • Third, I am providing an RSS newfeed to allow you to keep informed regarding news in biology. Each week you should choose one of these articles, summarize it and discuss how you think it illustrates one of the four Big Ideas.

Big Idea 1: The process of evolution drives the diversity and unity of life
Big idea 2: Biological systems utilize free energy and molecular building blocks to grow, reproduce and to maintain dynamic homeostasis.
Big idea 3: Living systems store, retrieve, transmit and respond to information essential to life processes
Big idea 4: Biological systems interact, and these systems and their interactions possess complex properties.

  • Fourth, You will also be using it to create your own review for the exam.

  • Finally, Who knows where this WIKI will take us?? There are many different uses, so we will be open to new ideas as they arise. Feel free to make suggestions!
