The need to know

• Bioengineering involves the use of technology to
  alter or improve living things.
• All cells make proteins
• Living things need a wide variety of proteins to
  carry out the processes that keep them healthy
  and alive.

9
Various diseases can destroy groups of cells that
produce essential proteins.

• For example diabetes is often caused by the lack
  of a protein called insulin.
• In people with this kind of diabetes, many or all
  the cells that produce insulin have died.

• Sohow can doctors treat this problem?....replace
  the protein??...Well, it is not that easy!
• So why so hard?

10

• Proteins may be hard to produce.
• There might not be enough of the protein to treat
  all the people who need it.
• This is where the bioengineer comes in

11
First.a few things you need to know

• Genes are instructions in the cellfor the cell.
• If the cells that make insulin die, the genes
  cannot do their job, and the protein will not be
  made.

12

• Bioengineers found a way around thisthey
  transfer proteins needed into bacteria cells (and
  other types too) The bacteria cells that contain
  the recipe work as factories to make more of the
  protein.

• But, why bacteria?
• Bacterias multiply quickly.
• When they multiply, they pass their genes to the
  next generation.
• If the bacteria have a gene for a human insulin

13

• Other bioengineering bacteria are used to make
  drugs to treat diseases caused by viruses.
• One example is interferon.

14

• Interferon is used to treat viral diseases such
  as life threatening influenza. ( the flu)
• Interferon stimulates the body to make substances
  that stop infected cells from producing new
  viruses.

15
Bioengineering in Agriculture

• It can make crops resistant to diseases,
  herbicides, and frost.
• Crops for food is altered so that it is more
  nutritious and better tasting.

• The best results have been obtained from using
  bacterium that infects broadleaf plants. They are
  programmed to carry useful genes into plants.

16
Herbicides

• Herbicides are substances used to kill weeds.
• Some are made for killing weeds only and will not
  damage crops.

• One risk- herbicides that are crop resistant,
  might be considered weeds elsewhere (corn plant
  in a cotton field).

17
Food

• Bioengineered food must be tested for safety.
• One risk is moving genes from one species to
  another and causing allergic reactions in people.
• If everyone plants the same type of crop in one
  area and that type is vulnerable to disease, they
  could lose all of that crop.

18
Biofuels

• A fuel made from living things.
• Biofuels substituted for some of the gasoline
  burned in automobile engines.

• With the help of bacteria, ethanol can be made
  from cellulose, a substance in the hard fibers of
  plants

Section 4 Science and Engineering
Technology and Society

• Technology provides solutions for many types of
  social, political, and economic needs.
• Intended Benefit An intended benefit is the
  positive purpose for which a technology is
  designed to be used.
• Unintended Consequences Unintended consequences
  are uses or results that engineers do not
  purposely include in the design of products. An
  unintended consequence can be beneficial.

Section 4 Science and Engineering
Bioengineering, continued

• Assistive Bioengineering Bioengineered
  technologies can be classified as either
  assistive or adaptive.
• Assistive technologies are developed to help
  organisms with changing them.
• Adaptive bioengineered products change the
  living organism.

21
Assistive Technology can include products for
people with communication Impairments
22
WHAT IS ASSISTIVE TECHNOLOGY?

• Devices, software, tools, and services that
  allow people who have physical and/or cognitive
  limitations to do tasks that would otherwise be
  significantly difficult for them to do.

23
Tech Act

• Assistive technology is any item, piece of
  equipment, or product system, whether acquired
  commercially off the shelf, modified, or
  customized, that is used to increase, maintain,
  or improve functional

24
A.T. is a device or a service
25
A Device

• Any item, piece of equipment, or system that
  increases, maintains, or improves the functional
  capabilities of people with disabilities.
• A.T. devices help people function longer and
  better.

26
We all use A.T.
