7.3 ATP provides energy for cellular work. Objectives Describe the structure of ATP and how it stores energy. Give examples of work that cells perform.
Cycles of Matter. Cycles of Matter: Why? Because we have a fixed amount of STUFF (matter) on this planet, and no new stuff is being added from the universe.
What things do organisms need to stay living?. All organisms need… Water – Most organisms are 70% water. – Gain water from fluid and food intake Air –
4.1 Chemical Energy and ATP KEY CONCEPT All cells need chemical energy.
Compounds of Life Biological Molecules By Joseph A. Castellano, Ph.D. RESEED Silicon Valley Reference: Focus on Physical Science, Glencoe/McGraw-Hill,
1. Carbon is the second most abundant element in living organisms. 2.Carbon can share four electrons, therefore it can bond to four additional atoms.
Chemical Compounds in Cells Essential Questions: What are elements and compounds? What are the main kinds of organic molecules in living things? How is.
Organic Chemistry Recognizing the 4 main classes of organic molecules.
Biochemistry of Cells 1. Carbon-based Molecules Although a cell is mostly water, the rest of the cell consists mostly of carbon-based molecules 2 Organic.
Carbohydrates Properties Controlled by Structure.
All organisms have the same basic needs: Food Water Air Shelter.
Energy Flow Through an Ecosystem Food Chains, Food Webs, Energy Pyramids.
Earths 4 Spheres air life water earth/rocks The Water Cycle.
End Show 2–3 Carbon Compounds Slide 1 of 37 Copyright Pearson Prentice Hall Macromolecules Four groups of organic compounds found in living things are:
How Plants Get Their Food (1). How do plants get their food ? The soil was watered but nothing else was added. After 5 years, the tree had gained 74kg.
Photosynthesis Photosynthesis is the process by which plant cell’s capture energy in sunlight and use it to make food. Autotrophs are organisms that make.

1.3.1 Function of Food Why do we need food?. Need to know The Function of Food Three reasons for requiring food 2.
Biochemistry Notes Biochemistry Biochemistry Study of science that explores how properties of CHEMICALS make life possible.
Oxygen Cycle. Required for Life All living things use oxygen or depend on organisms that use oxygen in some way.
Chapter 2: How Cells Function Have already learned: -All living things are made of cells -Cells need energy to sustain life -Plant and animal cells have.
