The lists are […]

Biochemistry- Protein Structure

Proteins – linear polymers of amino acids – peptide bond formation enables protein formation Size of a protein 50 to >30 000 amino acids Protein Formation: 1. Condensation reaction 2. Covalent bond (shares electrons) 3. No rotation around the bond 4. Atoms are co-planar 5. Restricts the possible folding patterns of the chain Polypeptides – […]

Living Environment Biochemistry

Carbohydrate any organic compound that is made of carbon, hydrogen, and oxygen and that provides nutrients to the cells of living things monosaccharide a simple sugar that is the basic subunit of a carbohydrate disaccharide A double sugar, consisting of two monosaccharides joined by dehydration synthesis. polysaccharide a complex molecule composed of three or more […]

Biochemistry of Cells Test

What is the most abundant organic compound on Earth? Cellulose Besides water, what other substance makes up most of the cell? Carbon-based molecules (a.k.a Hydrocarbons) Carbon has how many outer electrons? Four Because carbon has four outer electrons, it can form ___________ bonds by sharing these electrons. covalent Carbon and hydrogen make up compounds called […]

What is a polar molecule? A polar molecule is a molecule with both a positive and negative charge Adhesion Water molecules stick to other substances Cohesion Water molecules stick to each other Surface tension Property allowing liquid to resist external Force Universal solvent Water is capable of dissolving more substances than any other liquid Density […]


Osmosis – movement of water molecules from an area where there is more H2O -> less water through a selectively permeable membrane Isotonic Solution – same amount of solute as that found inside the cell – water moves in and out at equal rate Animal Cell Isotonic – no change in cell Plant Cell Isotonic […]



Chapter 3 Section 2: Biochemistry-Review

Compare the structure of monosaccharides, disaccharides, and polysaccharides. A monosaccharide is a monomer of carbohydrates. 2 monosaccharides can combine to form a double sugar, or a disaccharide. A polysaccharide is a complex molecule composed of 3 or more monosaccharides. How are proteins constructed from amino acids? Amino acids link together to to form proteins. How […]

Biological explanations to OCD – biochemistry

Overview of serotonin Research has revealed a link between OCD and insufficient levels of serotonin. Serotonin plays a role in the regulation of mood, aggression, impulse control, sleep, appetite, body temperature and pain. Evidence for this comes from the observation that antidepressant drugs can relieve the symptoms of OCD. Selective serotonin reuptake inhibitors (SSRI’s) are […]

Chapter 16 Biochemistry

The citric acid cycle has two other names: Tricarboxylic acid cycle, Kreb’s cycle Which of the following is(are) not involved in krebs cycle? Pryruvate and Glyceraldehyde 3-Phosphate In biochemistry, cellular respiration is that cells consume O2 and produce CO2. It occurs in four major stages, and in the second stage, the acetyl groups are fed […]

SBI4U: Biochemistry

isotonic when the concentrations of ECF (extracellular fluid) are the same as the ICF (intracellular fluid) hypotonic there is more water than solute in the environment hypertonic there is more solute than water in the environment ATP adenosine triphosphate carbohydrates, lipids, proteins, and nucleic acids 4 compounds of life required by our cells in order […]

Biology Unit 1- Biochemistry

What is biology The study of living things What is a monosaccaride One sugar What is the function of carbs Store and release energy Provide the least amount of energy but the easiest to break down What 3 groups are carbs classified into? Monosaccharides-one sugar(glucose, galactose, fructose Disaccharide- Simple sugars(2 sugars- Table sugar, Maltose, Lactose […]

Bio Keyterms – Unit 3 Biochemistry

carbon the main element in all organic molecules; often links to itself, forming chains/branched molecules/rings organic something is _____ if it contains C [except NOT CO2] hydrocarbon chain of carbon with hydrogens located on periphery of molecule functional group a portion of a molecule that behaves in predictable ways and is often involved in bond […]

organic compounds contain carbon inorganic compounds do not contain carbon cohesion water sticks to itself adhesion water sticks to other things function of carbohydrates energy carbohydrates polymers made of simple sugars glucose C6H12O6 glucose primary source of energy disaccharide must be broken down before they can be absorbed by blood cells sucrose glucose + fructose […]

Biochemistry- Carbohydrates Test

Saccharides is synonymous to: Carbohydrates What is the base formula of carbohydrates, from which they got their name? (CH₂O)n think of them as hydrates of (H₂O) of carbon (C) where C>2… N is some integer, which gives them a factor to multiply in What are three functions that carbohydrates can have in living systems besides […]

Unit 1: Biochemistry and Cells (Metabolism)

Absorption spectrum The range of a pigment’s ability to absorb various wavelengths of light; also a graph of such a range. Accessory pigment A photosynthetic pigment that traps light energy and channels it to chlorophyll a, the primary pigment, which initiates the reactions of photosynthesis. Accessory pigments include the carotenoids, phycobiliproteins, and chlorophylls b, c, […]

Adhesion intermolecular attraction between unlike molecules Carbohydrate A macromolecule that contains atoms of carbon, hydrogen, and oxygen in 1:2:1 ratio and serves as a major source of energy for living things Catalyst A substance that enables a chemical reaction to proceed at a faster rate by lowering activation energy Cohesion The intermolecular attraction between like […]

Biochemistry and the Unity of Life: Problems

All organisms are remarkably similar at a biochemical level. E.coli and elephants. What is meant by the phrase “unity of biochemistry”? Suggests that all organisms on Earth are derived from a common ancestor. What are the implications of the unity of biochemistry? DNA is double stranded, its sugar is deoxyribose, and it contains the base […]
