Differentiate between adaptive and assistive bioengineered products.

Differentiate between adaptive and assistive bioengineered products.

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.

Differentiate between adaptive and assistive bioengineered products.

I. BioengineeringA.The application of

engineering to living things such as humans and plants

Differentiate between adaptive and assistive bioengineered products.

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

Differentiate between adaptive and assistive bioengineered products.

2. Adaptive Bioengineering

a. engineering that results in a product

or process that changes

living things

b. artificial heart, artificial organs,

cochlear implants

Assistive Bioengineering

Adaptive Bioengineering

Differentiate between adaptive and assistive bioengineered products.

I. Bioengineered ProductsA. Medicine – good genes or proteins are

manufacture to replace bad ones using bacteria

1. Examples- insulin, interferon2. Genetic engineering – any change to

an organism’s DNA

3. Gene splicing – replacing bad or undesired genes with working or desired genes

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

Differentiate between adaptive and assistive bioengineered products.

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
