DESCRIPTION

Homeostasis B. Homeostasis is the process of maintaining internal conditions within a narrow range that varies only slightly over time  F37  C Example: Human body temperature must stay at about 98.6  F (or 37  C) in order to stay alive and healthy. If body temperature gets too hot or too cold, we would get sick and may even die. II. Basic Biochemical Processes of Living Things Biochemical processes energy nutrients necessary for life A. Biochemical processes are the chemical processes that occur in living things. All organisms need both energy and nutrients to carry on the internal biochemical processes that are necessary for life.

Use color and be as detailed as possible! Last, write a summary (1-2 paragraphs) comparing and contrasting the processes, describe the organisms involved and how the regulation of these life processes contributes to homeostasis. Use the pink construction paper in the back of the room. Provide references changing environment A. All living things are made up of organized structures and systems. To stay alive all organisms must keep their biological systems stable even though they live in a changing environment. adapt homeostasis In order to keep their systems stable, organisms must continually adapt and respond to changes in the environment. The internal stability that organisms maintain is called homeostasis. I. Homeostasis s Homeostasis B. Homeostasis is the process of maintaining internal conditions within a narrow range that varies only slightly over time F37 C Example: Human body temperature must stay at about 98.6 F (or 37 C) in order to stay alive and healthy. If body temperature gets too hot or too cold, we would get sick and may even die. II. Basic Biochemical Processes of Living Things Biochemical processes energy nutrients necessary for life A. Biochemical processes are the chemical processes that occur in living things. All organisms need both energy and nutrients to carry on the internal biochemical processes that are necessary for life. photosynthesiscell respiration 1. Two very necessary biochemical processes that must occur for all life forms to continue are photosynthesis and cell respiration. a.Photosynthesis energysunlight Plantsalgae single-celled organisms a.Photosynthesis is the process by which the energy from sunlight is stored in the chemical bonds of organic (containing many carbons) molecules such as carbohydrates. Plants, algae, and many single-celled organisms carry out photosynthesis. b.Cell respiration chemical energy All living organisms b.Cell respiration is the process by which the chemical energy stored in nutrients is released for use in cells. All living organisms carry out cellular respiration. What really happens to the food we ingest and digest? carbslipidsproteins Remember those carbs, lipids, and proteins? This unit will explain how we take our food and convert it into something we can use. That something is GLUCOSE Once we have our glucose our bodies (our cells) are actually able to break its many high energy storing bonds through a series of complex reactions!! CELLULAR RESPIRATION Remember... Cellular Respiration Cellular Respiration is a process that occurs continuously in the cells of ALL ORGANISMS that includes plants, protists, fungi, and all animals!!! What you will know? CELLULAR RESPIRATIONhttps://www.youtube.com/watch?v=-Gb2EzF_XqA Cellular respiration- a series of chemical reactions to break down the chemical bonds of food molecules. Packages this energy into a usable form called ATP (adenosine triphosphate) I. ENERGY Energy is the ability to do work need energy to stay alive! All organisms need energy to stay alive! Organisms break down food which releases energy Some of the energy is released as heat to keep organisms warm cellular respiration Release of energy stored in food inside the cell is called cellular respiration chemical energy Living things can only use the chemical energy form. high energy chemical bonds (in ATP) Part of the energy is stored as high energy chemical bonds (in ATP) Does this look familiar to anyone? II. ENERGY COMES FROM FOOD! ATP and ADP energy released in cellular respiration is packaged in molecules called ATP and ADP adenosine triphosphate ATP = adenosine triphosphate 3 (3 phosphate groups holds more energy) adenosine diphosphate ADP = adenosine diphosphate 2 (2 phosphate groups less energy stored) Phosphorylation third phosphate phosphorylation. When the third phosphate group is removed and bonded to another compound, it is called phosphorylation. During Active transport, ATP is used to change the shape of some proteins for transport in and out of the cell H Adenosine diphosphate Adenosine triphosphate III. AEROBIC RESPIRATION (in the mitochondria of a cell) Requires free oxygen Requires free oxygen (not combined with any other compound) oxidizes (loses electrons and breaks down energy) Glucose completely oxidizes (loses electrons and breaks down energy) Maximum amount Maximum amount of energy is removed from glucose Occurs in almost all plant and animal cells ANAEROBIC RESPIRATION (in the cytoplasm of the cell) Process without oxygen Process without oxygen Cell receives little of the chemical energy from the glucose Examples are yeast, bacteria and fatigued muscle cells REACTIONS TO KNOW The glucose produced during photosynthesis is used in two ways: One way glucose is used is to build complex molecules a. One way glucose is used is to build complex molecules. long chains called starch (a carbohydrate). Plants store a lot of the glucose they make by joining many glucose molecules together in long chains called starch (a carbohydrate). Another way glucose is used is to produce ATP molecules b. Another way glucose is used is to produce ATP molecules. The energy molecule ATP is produced during cell respiration when glucose is broken down into carbon dioxide and water. ATP is the fuel for life. * Memory device: ATP is a molecule that contains All The Power. GLYCO GLYCOLYSIS (Does not require oxygen) in the cytoplasm of the cell and occurs in both aerobic and anaerobic respiration takes place in the cytoplasm of the cell and occurs in both aerobic and anaerobic respiration Glucose + 2ATP 2 Pyruvic acid + 4ATP Glucose + 2ATP 2 Pyruvic acid + 4ATP (the splitting of glucose) Glucose 2 Pyruvic acid + 2 ATP 2 ATP are needed to kick start the process. SO WHAT IS THE NET GAIN IN ATP?

The Krebs Cycle (Citric Acid Cycle) pyruvic acid is broken down into carbon dioxide During the Krebs Cycle, pyruvic acid is broken down into carbon dioxide while producing high energy electrons to be used for generating large amounts of ATP! glycolysis pyruvic acid final two additional steps of Aerobic respiration After glycolysis (splitting of glucose) occurs in the cytoplasm 90% of the chemical energy still remains in the high energy electrons of pyruvic acid. If oxygen is present then the pyruvic acid travels to the mitochondria for the final two additional steps of Aerobic respiration. The Electron Transport Chain B. The Electron Transport Chain (in the mitochondria) convert ADP to ATP Electrons from the Krebs Cycle help convert ADP (Adenosine Diphosphate) to ATP (Adenosine Triphosphate) and produces water in the process! KREBS CYCLE If oxygen is present Process moves to the mitochondria carbon and oxygen atoms are removed they produce CO 2 that leaves the cell and is sent to the lungs to be exhaled ELECTRON TRANSPORT CHAIN hydrogen (H+) remaining hydrogen (H+) O 2 combines with free O 2 to produce O2O2 O2O2 O2O2 O2O2 O 2 breathed in C 6 H 12 O 6 GLUCOSE C 6 H 12 O 6 + O 2 O2O2 CO 2 + H 2 O + 36ATP NET GAIN Aerobic (O 2 ) Respiration H2OH2OH2OH2O PYRUVIC ACID (C-C-C) enzymes O2O2 O2O2 O2O2 GLYCOLYSIS (GLYCOLYSIS) Uses 2 ATP the cytoplasm In the cytoplasm CO 2 + H 2 O + 38 ATP https://www.youtube.com/watch?v=JnQqbMg74Hk Cell respiration = is a series of chemical reactions that breakdown the chemical _________ of food molecules to release __________ in the usable form of ________. ____________ - requires oxygen ____________ - no oxygen present __________ (C 6 H 12 O 6 )
