6.16 Nectar To Honey Conversion Flashcards
How is the nectar collected by the bee?
Sucked up by mouth parts –> stored in crop –> small amount may be passed to preventriculus –> offloaded to a reciever –> owers water content –> deposits in cell
What is the crop capacity?
100mg
What is the average nectar load in the crop?
40mg
How do nectar processeors reduce the water contnet?
They will recive a nectar load, move to an empty part of the nest and place droplets on her tounge. She will expose it to air and evaporate the water
What percentage of water does the nectar reach before it is sealed>
0.18
What is the equation of honey to nectar?
Sucrose (C_12 H_22 O_11 )+ H_2 O ↔Glucose (C_6 H_12 O_6 )+Fructose (C_6 H_12 O_6)
What is the name of the reversible reaction of nectar to honey>
Hydrolysis
What is the enzyme sucrase for and why is it beneficial?
It breaks glycosidic bonds which would take a long time normally. It turns 1 molecule of sucrose into 1 glucose and 1 fructose. This turns it into simple inverted forms which are more easily digstible
What gland produces the enzyme sucrase?
Hypophanrageal glands
What are the two main steps in turning nectar to honey?
Reducing the water content, changing the compostion
What does the enzyme glucose oxidase do?
Breaks glucose into hydeogen peroixde and gluconic acid. Hydrogen perioxide destorys bacteria, gluocnic acid makes the honey acic to avoid bacterial growth due to nectar habing a high water content
What gland secretes the glucose oxidase?
Hypophanrageal glands
