Cellular Respiration and Photosynthesis -- Important Ingrid Waldron, Photosynthesis and Cellular Respiration Song Photosynthesis and Cellular Respiration Song You will be writing a song with lyrics about photosynthesis and cellular respiration.
You will be in groups for writing and presenting the song, and you will be in groups of up to 3. Look at the following requirements and rubric before starting your song. Objectives: 1. Using a simple example, explain why it is necessary to have several steps for the highest success in energy flow from the sun through all life. Provide simple and complete definitions of important terms, and examples of photosynthetic organisms.

You can often see energy at work in living things—a bird flies Cellular respiration occurs in the cells of all living things. It takes place in the cells of both autotrophs and heterotrophs. All of them burn Those organisms that are capable of photosynthesis are known as producers, and all the remaining organisms can be termed consumers.
Photosynthesis can be defined as the transfer and storage of solar energy to a chemical form called glucose a type of sugar. A testcross is used to determine the phenotype of an individual. For example a purple flower may have one of the following two genotypes PP or Pp. A test cross requires you to cross a homozygous individual pp. Can you please go over the basics of the endocrine system?
Information, formation et consultation
The following video on the endocrine system should help. What is the difference between cyclic and non cyclic photosynthesis? This will move more protons to the inside of the thylakoid and will therefore create more ATP. The following video on the Tour of a Cell should help. Do we need to memorize the formulas and be able to use and understand them well for the AP Exam? There is no need to memorize any of the formulas that are on the formula sheet. You should know how to use all of the formulas.
What are the differences between the lac and trp operons? The following video on the operon should help. I discuss both the lac and trp operons.
The following video on proteins should help. Good question. You should definitely look at the FRQ's over the last few years to see what they are like. Here is a link to the old questions. How do I structure the essays? All of the questions must be written in essay form e. Be wary of words like discuss and explain. These words will require longer answers. Solve each of the alleles separately. For example what are the odds of the parents listed above creating the following offspring AABbCc. Solve each letter individually. Multiply all of the fractions to arrive at the correct answer.
The following video on the Molecules of Life should help. Each parent gives half of their chromosomes to their offspring. This pumps moves Sodium outside the cell and Potassium inside. It is used to maintain the potential difference in neurons. Transformation Transduction and Conjugation. The following video should help. Can you explain the purpose of alternation of generations in plants?
Plants like animals alternate between haploid and diploid stages. The diploid version of a plant is referred to as the sporophyte and the haploid is the gametophyte. Could you explain entropy, enthalpy, Gibbs free energy, and the equation that connects them?
The following video on Gibbs Free Energy should help. What's your favorite concept to study in AP Biology? I enjoy all of the topics but when I study for fun I tend to focus on evolution.
Cellular Respiration Free response question and answer
Include a description of mitosis and cytokinesis, and of the other phases of the cell cycle. Do Not include meiosis. A laboratory assistant prepared solution of 0. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer a a description of how you would set up and perform the experiment: b the results you would expect from your experiments: and c an explanation of those results based on the principles involved.
Be sure to clearly state the principles addressed in your discussion. Cells transport substances across their membranes. Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells.

Include in your discussion the major reactions, the end products, and energy transfers. The rate of photosynthesis may vary with changes that occur in environmental temperature, wavelength of light, and light intensity. Using a photosynthetic organism of your choice, choose only ONE of the three variables temperature, wavelength of light, or light intensity and for this variable. Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule.
