Carbohydrates

• The most common form of this type of organic molecule is a triglyceride, which is a Glycerol with 3 fatty acid chains; supplies twice as much energy per gram as compared to carbohydrates.

• Lipids

• Chain of Amino acids held together by peptide bonds. Functions include enzymes, transport proteins and receptors in the cell membrane, used to make antibodies and hormones.

• Translation produces ____________

• Protein

• Made of Nucleotides. Contains genes that code for proteins. DNA - double-stranded nucleic acid and RNA is single-stranded.

• Nucleic acids

• What happens to a cell placed in a hypertonic solution?

• Water leaves the cell by osmosis and it shrinks.

• Which type of transport moves molecules with the concentration gradient, does not require energy?

• Passive transport

• Which type of transport moves molecules against the concentration gradient; requires energy

• Active transport

• Which organelle makes protein?

• Ribosome

• Which organelle produces ATP for the cell to use as energy?

• Mitochondrion

• Controls what enters and leaves the cell by selective permeability.

• Cell membrane

• This is the basic structure of the cell membrane (phosphate heads make the inner and outer surface, fatty acid tails make the interior)

• Phospholipid bilayer

• The synthesis of larger molecules; requires energy

• Anabolism

• The breakdown of large molecules into smaller ones; energy is released when bonds are broken

• Catabolism

• Enzymes speed up chemical reactions by lowering the____________

• Activation energy

This mechanism helps maintain homeostasis by keeping physiological values within a narrow range

Negative feedback

• The 3 phases of this are: glycolysis, citric acid cycle, and electron transport chain. Produces 36-38 ATP from one molecule of glucose.

• Cellular respiration

• Which phase of cellular respiration is anaerobic?

• Glycolysis

• What is produced from the carbon atoms that are removed from glucose during cellular respiration?

• Carbon dioxide

• When muscle cells are working so hard that they use up all the available oxygen, they switch to_______

• Fermentation (anaerobic respiration)

• The production of red blood cells, white blood cells and platelets by the red marrow in spongy bone.

• Hematpoiesis

• Transcription produces ________

• RNA

• Translation produces __________

• Protein

• This tissue covers surfaces, and its functions include protection, secretion and absorption.

• Epithelium

• One of the reason’s for smoker’s cough is that these get damaged on the cells that line the trachea and bronchi.

• Cilia

• This forms the epidermis, and also lines the oral cavity, esophagus, vagina and anal canal. Because of its many layers of cells, it protects the underlying tissue.

• Stratified squamous epithelium

• This cell is found in connective tissue and releases heparin and histamine during an inflammatory or allergic reaction.

• Mast cell
