1 809 Differentiate between adaptive and assistive bioengineered products.

2 Key concepts/skills: Level 1: Define key vocabulary. Level 2: Differentiate between adaptive and assistive technology. Level 3: Identify examples of biofuels, bioengineered medicines, and bioengineered pest management, and explain why each is either assistive or adaptive technology.

3 Key vocabulary: Bioengineering Biofuels Bioengineered food Assistive bioengineering Genetic engineering Gene splicing Bioengineered medicine Adaptive bioengineering Pest management

4 I. Bioengineering A.The application of engineering to living things such as humans and plants

5 1. Assistive Bioengineering a. engineering that results in a product or process that helps living organisms but does not change them permanently b. hearing aid, glasses, prosthetic limbs, band aids

6 2. Adaptive Bioengineering a. engineering that results in a product or process that changes living things b. artificial heart, artificial organs, cochlear implants

7 Assistive Bioengineering Adaptive Bioengineering

8 Differentiate between adaptive and assistive bioengineered products. I.Bioengineered Products A. Medicine – good genes or proteins are manufacture to replace bad ones using bacteria 1. Examples- insulin, interferon 2. Genetic engineering – any change to an organism’s DNA 3. Gene splicing – replacing bad or undesired genes with working or desired genes

9 Differentiate between adaptive and assistive bioengineered products. B. In Agriculture – making crops resistant to disease herbicide and frost 1. Herbicide resistant crops (corn) 2. Plants like tomatoes that will ripen on vine and stay fresh longer

10 C. Biofuels – Ethanol is a clean burning fuel for engines made from plants. 1. Cellulose > sugars > ethanol 2. Bacterium control this process 3. Problem is which plants should be used to make ethanol? 4. Plants used are corn, sugar, sugar beets, switchgrass, algae
