Enzymes are used in all metabolic reactions to control the rate of reactions and decrease the amount of activation energy necessary for the reaction to take place. Enzymes are specific for each reaction and are reusable. The chemical an enzyme works on is called the substrate. An example of a substrate is hydrogen peroxide.
What Is the Basic Unit of Life?
An example of an enzyme is catalase. Many scientists call this temporary bond the induced fit model. This lab looks at how abiotic nonliving or biotic living factors can change or influence enzymatic reactions. There are many forms of this lab using many different types of equipment. One version uses hydrogen peroxide as the substrate that is broken down by the enzyme catalase. A couple of the variables chosen to test are varying the amount of substrate, varying the amount of enzyme, and varying the temperature or pH. A control is set up for each lab. One way is to substitute water for the enzyme. Lactase Enzyme: Lactase The second lab is about photosynthesis. In eukaryotes, photosynthesis takes place in the chloroplast. There are two general processes of photosynthesis: 1 Light-dependent reaction often called the light reaction and this takes place in the thylakoid membranes 2 Light Independent reaction often called the dark reaction or Calvin cycle and this takes place in the stroma or fluid area of the chloroplast.

The process of photosynthesis occurs in a series of steps regulated by enzymes. During photosynthesis, light energy is captured to build carbohydrates that are full of energy stored in the chemical bonds. Autotrophs are organisms that capture free energy from the sun through photosynthesis and chemosynthesis and heterotrophs from the carbon products like carbohydrates of other organisms. Living systems require free energy and matter to grow and to reproduce. A common version is called the floating disc lab. In your classroom, you may have used ivy or baby spinach leaves and punched out discs and used a syringe to sink the discs and timed how long it took for the discs to float again. Photosynthesis tutorial and virtual lab review: Photosynthesis lab: Photosynthesis The following is a simulation by Jon Darkow. This is an excellent review of content and helps you work on your science practice skills.

Photosynthesis Simulation: Photosynthesis The third lab is about cellular respiration. Living systems require energy to grow and reproduce. If organisms are lacking or deficient in energy, this deficiency can cause harm to the organism or to the population or even the ecosystem level. Different organisms use different strategies to store and preserve energy, often called free energy. Autotrophs are organisms that capture free energy from the sun through photosynthesis and chemosynthesis and heterotrophs obtain energy from the carbon products like carbohydrates of other organisms.

In the process of cellular respiration, At the cellular level, the intake of oxygen gas and the output of carbon dioxide gas is associated with the production of ATP and this process is called cellular respiration. ATP is generated by mitochondria within the cell. During cellular respiration, the energy stored within macromolecules such as glucose is released and utilized to phosphorylate add a phosphate to ADP, producing ATP. In the presence of oxygen, glucose can release large amounts of energy. The process of cellular respiration also produces water and carbon dioxide gas as waste products. Plants and animals are both examples of aerobic organisms. Cell respiration takes place in the mitochondria in eukaryotic organisms and has three general steps: 1 Glycolysis anaerobic -- no oxygen required in the cytoplasm 2 Krebs or Citric Acid Cycle aerobic -- requires oxygen in the mitochondrial matrix and 3 Electron Transport Chain that is aerobic as well. There are many versions of this lab.

One version uses respirometers you can make out of a syringe or other materials and place germinating, non-germinating seeds and beads as a control in them. You measure the respiration rate by measuring oxygen consumption. These are an excellent review of content and help you work on your science practice skills. In Unit 2 the various types of carrier proteins involved in facilitated diffusion are an example of cell signaling. Also in unit 3, light is used to trigger a response to start the process of photosynthesis light-dependent reaction.

You will learn how cells use energy, transfer information and replicate by using cellular communication. One basic pathway for this process is called the signal transduction pathway. There are three steps. The signal transduction process allows cells to maintain homeostasis by being able to respond to changes to the environment. Also, signal transduction plays a major role in regulating the cell cycle that is important for life. Blood sugar regulation production of insulin and glucagon , neurotransmission, the immune system with helper and killer T cells are examples of cell communication you may know. There is one major recommended lab. It is about cell division: mitosis and meiosis. For the mitosis lab, a common version is to use onion root tips and by using different chemicals lectin or caffeine are the common ones to see if you can inhibit or stimulate onion root tip growth. One way is to cut the tips and stain them and count to see at what stage of mitosis the individual cells are or to have the root tips cut to the same length, measure them and see if there is a change in length over time.

Most teachers do the meiosis portion of the lab with Unit 5. Please note: Only two examples are provided here. One does a great job reviewing Cell Cycle Regulation and the other is about p53 genes and cancer. It is used by bacteria. This book is a fantastic read and is relevant today because she had some of her cervical cancer tissue removed with her knowledge. If interested in the Henrietta Lacks story: Henrietta Lacks Unit 5: Heredity You will learn about the concepts and processes associated with heredity. These include the passing on or transmission of genetic information using chromosomes from one generation to the next using the process of meiosis. Meiosis is a process that makes certain genetic diversity which is important for speciation to occur. Meiosis is a process where a single cell divides two times to form four non-identical cells with half the original amount of genetic information.

These particular cells are our sex cells; egg and sperm. They are haploid n which means they have half the number of chromosomes as the parent cell. The parent cell is called diploid 2n. You study Mendelian and Non-Mendelian genetics and learn about patterns of inheritance. Meiosis is studied and its importance to our genetic variation. Lastly, you learn about how the environmental factors like lack of oxygen, alcohol, etc. He found out that genes come in pairs and are inherited in genes, one from each parent. Mendelian genetics studies three main ideas or laws.

This deals with two genes 3 Law of dominance, which means one character or trait is dominant and the other is recessive, the dominant form of the trait will be expressed Non-Mendelian genetics simply put do not follow Mendelian genetics laws. Listed below are a few examples: Incomplete dominance: For example, Red and White flowers are crossed and form pink flowers. Codominance: Both genes expressed equally. For example blood typing: AB blood typing is an example. Sex-linked: Usually X linked which means the trait usually shows up in males. An example of this is red-green color blindness.

Wet Mount of an Onion Cell Put a drop of water onto the microscope slide. It should be very thin and may curl up on itself. Place the onion sample into the drop of water on your slide. You may need to use the dissecting needle to do this. Place a coverslip onto the slide. You probably will not see the cells at this power. Switch to low power 10x. Cells walls should be visible: they will look like semi-clear grid lines. Once you think you have located a cell, switch to high power 40x and refocus. Sketch the cell at low and high power. Label the nucleus, cytoplasm, and cell wall of a single cell. Draw your cells to scale. Using the forceps, gently tear off a small piece of a leaf from Elodea. Place the Elodea leaf into the drop of water on your slide.
