bio molecules carbohydrates

Question 1

what is carbohydrates?

Answer 1

molecules made up of hydrogen carbon and oxygen and they are sugar units called saccharides

Question 2

3 types of saccharides?

Answer 2

monosaccrides- join together with other monosaccharides and form glycosidic bonds formed in condensation reactions
dissaccharides
polyasccardies

Question 3

how many carbons are in the monosaccharide glucose

Answer 3

6
its the main substrate for respiration

Question 4

what product does 2 alpha glucose makes

Answer 4

maltose

Question 5

what molecule does glucose and fructose make

Answer 5

sucrose

Question 6

what molecule does does glucose and galactose cause

Answer 6

lactose

Question 7

what are polysaccardies

Answer 7

two glucose units joined together

Question 8

glycogen?

Answer 8

1-4 glycosidic bonds
1-6 glycosidic bonds
it has a large number of side chains and its large and compact thus maxisming the amount of energy it can store

Question 9

amylose?

Answer 9

unbranched chains of glucose molecules joined by 1-4 glycosidic bonds and therefore coiled and very compact meaning it can store lots of energy

Question 10

amylopectin?

Answer 10

branched and is made up 1-4 and 1-6 glycosidic bonds and with many side chains it can release energy quickly

Question 11

cellulose?

Answer 11

cellulose is in cell walls and is composed of upside beta glucose joined with glycodic bonds
microfibrils are joined together by cellulose chains and hydrogen bonds and they provide structural support in plant cells

Question 12

hexose v pentose

Answer 12

hexose has 6 carbon chains
pentose has 5 carbon chains

Question 13

Answer 13

hexose - glucose molecules
pentose- ribose

Question 14

hexose
pentose
examples?

Answer 14

hexose - glucose molecules
pentose- ribose
