Resumo de Recurso

Questão 1

Questão
The general formula for carbohydrates is CnH2On.
Responda
  • True
  • False

Questão 2

Questão
Which of the following is NOT a main use of carbohydrates?
Responda
  • Energy store
  • Energy source
  • Structural molecule
  • Electrical insulation

Questão 3

Questão
Glucose is a [blank_start]hexose[blank_end] sugar.
Responda
  • hexose
  • pentose
  • ribose
  • tetrose

Questão 4

Questão
What is this molecule?
Responda
  • b-Glucose
  • a-Glucose
  • Ribose
  • DNA

Questão 5

Questão
This molecule is ribose. True or false?
Responda
  • True
  • False

Questão 6

Questão
In condensation between two sugars, an [blank_start]OH[blank_end] group and [blank_start]H[blank_end] group leave their monomers and become [blank_start]water[blank_end]. The monomers then join, forming a [blank_start]C-O-C[blank_end] bond. This is called a [blank_start]glycosidic[blank_end] bond. The resulting molecule can vary, for example: a-glucose + a-glucose = [blank_start]maltose[blank_end] a-glucose + fructose = [blank_start]sucrose[blank_end] a-glucose + B-galactose = [blank_start]lactose[blank_end] B-glucose + B-glucose = [blank_start]cellobiose[blank_end]

Questão 7

Questão
[blank_start]Starch[blank_end] is the main form of carbohydrate store in plants. It's made of [blank_start]amylose[blank_end] and [blank_start]amylopectin[blank_end], which are [blank_start]long[blank_end] chain [blank_start]a-Glucose[blank_end] chains. While [blank_start]amylose[blank_end] and [blank_start]amylopectin[blank_end] both have [blank_start]1,4-glycosidic bonds[blank_end], [blank_start]amylose[blank_end] coils into a helical shape, but [blank_start]amylopectin[blank_end] is branched out. Starch is [blank_start]insoluble[blank_end] so as to not affect the water potential of the cells it's stored in.
Responda
  • Starch
  • Sucrose
  • Sap
  • Glycogen
  • amylose
  • cellulose
  • glycogen
  • triglycerides
  • amylopectin
  • disaccharide
  • insulin
  • cellulose
  • long
  • short
  • double
  • a-Glucose
  • B-Glucose
  • Sucrose
  • a-Glucose and B-Galactose
  • 1,4-glycosidic bonds
  • 1,3-glycosidic bonds
  • 1,4-peptide bonds
  • amylose
  • glycogen
  • cellulose
  • triglycerides
  • amylose

  • cellulose
  • insoluble
  • soluble
  • inert
  • liquid

Questão 8

Questão
[blank_start]Glycogen[blank_end] is the main type of carbohydrate store in animals. It's a [blank_start]multi-branched[blank_end] [blank_start]a-Glucose[blank_end] polymer with 1,4- and 1,6-glycosidic bonds. It's highly [blank_start]compact[blank_end] so optimal for storage.
Responda
  • Glycogen
  • Cellulose
  • Glucose
  • Glucagon
  • multi-branched
  • unbranched
  • granular
  • insoluble
  • a-Glucose
  • B-Glucose
  • Maltose
  • compact
  • coiled

Questão 9

Questão
Which of the following descriptions are true about cellulose? Check all that apply.
Responda
  • Energy storage molecule
  • Highly fibrous
  • Insoluble
  • a-Glucose polymer
  • Unbranched chain called microfibril
  • Abundant in cell walls
  • 1,4-glycosidic bonds

Questão 10

Questão
Unlike plant cell walls, bacterial cell walls are made of peptidoglycan.
Responda
  • True
  • False
