Topic 7: Ecology (things to remember)

Question 1

Describe what happens in a fermenter

Answer 1

• fusarium with glucose syrup in aerobic conditions or in presence of oxygen
• microprotein is harvested/ purified

Question 2

What does fusarium do?

Answer 2

• fusarium is used to produce mycroprotein which is an alternative protein to meat
• it is grown on glucose syrup in aerobic conditions
• the biomass is then harvested and purified

Question 3

vasodilation

Answer 3

• blood vessels dilate allowing more blood to flow through capillaries to the surface of the skin
• more blood flows to the surface of the skin
• the rate of heat loss increases
• this causes body temperature to decrease

Question 4

vasoconstriction

Answer 4

• blood vessels constrict reducing blood flow to the surface of the skin
• less blood is lost by radiation
• this causes body temperature to increase

Question 5

Shivering

Answer 5

repeating muscle contractions
Muscles respire at higher rate
More heat is generated

Question 6

biotechnology

Answer 6

an area of biology that uses living systems to help create new or improved products
