Name:_________________________________ Nutrition Label Analysis When we read a nutrition label‚ the Calories tell us how much energy is stored in our food. Energy in food comes from 3 sources: fat (lipids)‚ protein‚ and carbohydrates. You will be analyzing the nutrition facts of an item to determine how much of the energy (Calories) comes from each type of carbon-based molecule. 1. How many grams of lipids (fat) are in your item? _________________________________________________________________________________________________

13A – Cells and Movement of Materials P1: Describe the microstructure of a typical animal cell and the main function of the cells components The microstructure of a typical animal cell is made up of various components‚ all of which play a vital role within the body. Each component has its own specific role that it performs in order for the cell to function and maintains the cell membrane. The main components of the cell include the cell membrane‚ cytoplasm‚ the nucleus‚ nucleolus‚ nuclear membrane

Unit 2 Lecture Study Guide 1) What are the parts of an atom? Where are the subatomic particles found? The atoms are the smallest units of matter with their own chemical characteristics. The atoms are divided into 2 parts. The first part is the central nucleus and the electron cloud. The central nucleus contains very heavy particles and the electron cloud contains very light moving particles. The subatomic particles are the protons‚ neutrons‚ and the electrons. They are located

There are different types of proteins. Fibrous proteins‚ for example‚ can be correlated with structure. Keratin is the main component of hair and nails that form protofibrils and consist of two pairs of alpha helices that are twisted together in a left-hand coil. The flexibility of keratin decreases as disulfide bond cross-links between protofibrils increases. Keratin is also found in skin and wool. Silk fibroin has the ability to form flexible‚ but the inextensive fibers are of great strength

system Enzyme: protein that serves as a biological catalyst changing the rate of a chemical reaction without itself being changed into a different molecule in the process Enzyme Catalysis: lowers activation energy Exergonic reaction: reactions that yield products that are rich in potential energy. Energy is absorbed form the surroundings as the reaction. Energy is stored in the covalent bonds of the product molecules. Facilitated diffusion: Use of specific transport proteins to move substances
