Flashcards in Living Organisms and Molecules Deck (38):
1

Cells are made up of....

e.g. mitochondria

Organelles

2

Found within the organelles of the cell are

ex: inner and outer membranes

supramolecular assemblies

3

Each of the supramolecular assemblies is composed of particular ________ (such as the protein, cytochrome c) and lipids

Macromolecules

4

Put these in order of progression: organism, precursor molecule, macromolecule

Precursor, macromolecule, organism

5

The structural and functional units of all living organisms

Cells

6

The outer membrane of a cell that separates it from its environment

It is selectively permeable to what, which includes proteins which aid in its specific cell functions?

Plasma Membrane

7

This part of a cell contains genetic material (DNA) that's stored and replicated here

Nucleus or Nucleioid

8

This part of the cell has aqueous cell contents, suspended particles and organelles enclosed by the plasma; contains metabolites, coenzymes, inorganic ions and enzymes

Cytoplasm

9

What are the two types of cells?

What groups do they divide into?

Prokaryotes and Eukaryotes

Prokaryotes divide into bacteria and archea, eukaryotes don't divide

10

This type of cell is a cell without a nuclear envelope, actually has a nucleoid. E. coli is the most commonly studied

Prokaryotes

11

This type of cell has a nuclear envelope

Eukaryotes

12

This type of prokaryote is found in soils, surface waters, and tissues of other living or decaying organisms

Bacteria

13

This type of prokaryote inhabits extreme environments such as salt lakes, hot springs and the ocean depths

Archea

14

The structures that make up a eukaryotic cell
are determined by the specific functions that
cell carries out. However, eukaryotic cells have
3 main components:

A cell membrane
A nucleus
Other organelles

15

The cell membrane is selectively permeable to different molecules by

Diffusion

16

______ in the membrane help actively transport material into and out of the cell

Proteins

17

Membrane functions are dependent upon the interactions between the ____ and _____ in the membrane

Lipids and Proteins

18

The membrane structure can be described as...

Fluid mosaic

19

_____ are formed from the membrane lipids such as a phospolipid molecule. Several lipid molecules come together in a packing arrangement to form it. Proteins are embedded within it

Lipid bilayers

20

The brain of the cell, it contains the information required to make most components of the cell

The Nucleus

21

The information in the nucleus is stored in the sequence of _______ found in ______

Nucleic acids found in chromosomes

22

These contain regulatory sequences involved in replication and transcription of DNA

Chromosomes

23

These maintain the life of a cell. A variety of membrane bound _____ with specific functions can be found in a eukaryotic cell

Organelles

24

Name 4 examples of membrane bound organelles with specific functions that are found in the cytoplasm of a cell

Mitochondria
Endoplasmic Reticulum
Golgi Complexes
Lysosomes

25

Membrane bound organelles in the cytoplasm of eukaryotes that contain the enzymes required for the citric acid cycle, electron transfer, fatty acid oxidation, and oxidative phosphorylation

Mitochondria

26

This organelle has an inner and outer membrane, and functions as the power plant of the cell

Mitochondria

27

An organelle that is a system of membranous tubules and sacs which functions as an intercellular highway, cells can move from one part of the cell to another

Endoplasmic Reticulum

28

The ER connects the ____ to the ____

nuclear envelppe to the cell membrane

29

This type of ER processes lipids and carbohydrates

Smooth

30

This type of ER is covered with ribosomes and processes proteins to be exported from the cell

Rough

31

Small dots associated with the rough ER, may also be free in the cytosol.

Ribosomes

32

Composed of specialized nucleic acids and proteins which are involved in protein synthesis inside the cell.

Ribosomes

33

T/F Macromolecules are polymers

True

34

What is the monomer of protein
Of nucleic acids
Of polysaccharides

Amino Acid residues
nucleotides
Sugar residues

35

The repository of genetic information

deoxy-ribonucleic acid (DNA)

36

The amino acid sequence of every protein molecule and nucleotide sequence of of RNA molecule is determined by a _________ in the cell's DNA

Nucleotide sequence

37

The transmitter of genetic information from the site of DNA to the site of protein biosynthesis

ribonucleic acid (RNA)

38

Which has a broader range of functions, RNA or DNA?

RNA
