why are Proteins essential

 Proteins are essential to the structures and functions of life 

100

how do carbohydrates served

Carbohydrates serve as a cell’s fuel and building material.

100

what type of molecule are lipids 

Lipids are hydrophobic molecules with diverse functions

100

what is nucleic acids job

Nucleic acids store, transmit, and help express hereditary information

100

how does A cell’s metabolic reactions transform energy

using ATP to drive cellular work.

200

how many amino acids do protein have 

20

200

what is glucose 

a common monosaccharide of central importance in the chemistry of life

200

are lipids hydrophobic or hydrophilic?

hydrophobic

200

what is gene

a discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA

200

enzyme function

Enzymes speed up a cell’s chemical reactions and provide precise control of metabolism.

300

what is amino acid 

an organic molecule containing a carboxyl group and amino group, serves as the monomer of proteins.

300

whats another word for monosaccharides 

simple sugars 

300

what is a fat?

large lipid made from two kinds of smaller molecules

300

 monomers that make up nucleic acids, what are they called?

nucleotides

300

Can you identify six different types of functions of proteins in a plasma membrane?

Attachment to the cytoskeleton and ECM, signal reception and relay, enzymatic activity, cell-cell recognition, intercellular joining, and transport

400

how many levels of structure does protein have

4

400

main fuel molecules for cellular work.

monosaccharides

400

do unsaturated fatty acid solidify at room temperature?

no

400

what is polynucleotide build from

monomers by dehydration

400

In the origin of a cell, why would the formation of a simple lipid bilayer membrane not be sufficient? What else would have to be part of such a membrane?

The membrane would need embedded proteins that could regulate the movement of substances into and out of the cell.

500

 by what process do you digest the proteins you eat into their individual amino acids?

by hydrolysis, adding a molecule of water back to break each peptide bond

500

what is a disaccharide

a sugar molecule consisting of two monosaccharides linked by a dehydration reaction

500

do saturated fatty acid soliodify at room temperature

yes

500

whats is a double helix

the form of native DNA, referring to its two adjacent polynucleotide strands interwound into spiral shape

500

Why is diffusion across a membrane called passive transport?

The cell does not expend energy to transport substances that are diffusing down their concentration gradients.
