Resources below are from a similar unit in 2017. I will update to reflect this unit.
Cool Science Videos:

Atom- The smallest possible unit of an element that still has the properties of that element. (made up of protons, neutrons and electrons)
Molecule: Made up of two or more atoms help together by sharing electrons (covalent bond)
Bond: Holds atoms together and contain energy. C-C and C-H bonds release more energy when they are broken then O-H.
Macromolecules: Carbohydrates, Lipids, Nucleic Acids, Proteins are all ORGANIC- contain Carbon and hydrogen
Organic Molecules have high energy C-C and C-H bonds. They provide energy for the cells as well as atoms for biosynthesis.
Carbohydrates: Used in the cells for quick energy. Makes up the cell wall of plants (cellulose), Source of Dietary Fiber (cellulose). How plants store energy (starch). Animals store energy on a SHORT term basis as glycogen.
Elements: Carbon, Hydrogen, Oxygen
Monomer: Monosaccharide Ex: Glucose, Fructose
Polymer: Polysaccharide Ex: Starch, Glycogen, Cellulose, Chitin
Lipids: Makes up the cells membranes. Used in cell for LONG term energy storage. Provides insulation for the body and helps to protect organs. Some hormones are lipids.
Elements: Carbon, Hydrogen, Oxygen
Examples: Triglyceride (made up of glycerol +3 fatty acids), Phospholipids, Cholesterol
Proteins: Enzymes speed up (catalyze) chemical reactions, Antibodies (help fight infection), Part of the cell membrane, Hormones, Build/repair muscle, make up hair/nails
Elements: Carbon, Hydrogen, Oxygen, Nitrogen (may contain others)
Monomer: Amino Acid (20 amino acids)
Polymer: Polypeptide (or Protein) Ex: Hemoglobin, Catalase, DNA Polymerase, Lactase
Nucleic Acids: Store genetic information that is used for making proteins. DNA, RNA (Nucleic acids are not on this test)
Elements: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus
Monomer: Nucleotide (Contains: Phosphate, Sugar, Nitrogenous Base)
4 Bases in DNA= Adenine (A), Thymine (T), Cytosine (C), Guanine (G)
A matches with T, C matches with G
4 Bases in RNA= Adenine (A), Uracil (U), Cytosine (C), Guanine (G)
A matches with U, C matches with G
Polymer: Nucleic Acid Ex: DNA, RNA
ATP- Molecule used by all cells as immediate energy. Chemical energy can be transferred to kinetic/heat energy for the cell to use.
Digestion: Breaking down a bigger molecule (polymer) into smaller pieces (monomers)
Biosynthesis: Building a bigger molecule from monomers.
Cellular Respiration: Done by all organisms
Aerobic Cellular Respiration:
C6H12O6 + 6O2 --> 6CO2 + 6 H2O (makes 34-38 ATP)
Take place in the mitochondria
Reactants: Sugar and Oxygen
Products: Carbon Dioxide and Water (and ATP)
The purpose of cellular respiration is to make ATP- which is used for immediate energy by the cell when a bond is broken and one phosphate leaves...turning ATP to ADP.
Aerobic Cellular Respiration (with oxygen) makes 34-38ATP
The 3 stages of Aerobic Respiration are Glycolysis, Kreb Cycle, and Electron Transport Chain.
Glycolysis takes place in the cytoplasm. It splits glucose into pyruvate and makes 2 ATP.
The Kreb Cycle takes place in the mitochondria. It makes some ATP and uses oxygen. It makes NADH and FADH2 to transport to the elecrton transport chain.
The electron transport chain makes LOTS of ATP. It uses oxygen to and causes ATP Synthase (enzyme) to add a phosphate onto ADP to make ATP. This takes place in the mitochondria.
Law of Conservation of Matter: Matter (atoms) cannot be created or destroyed...they can be rearranged to make new molecules.
Law of Conservation of Energy: Energy cannot be created or destroyed. It can be transferred from one type of energy (chemical energy) to another (mechanical energy)
-End of Content for Test for Dec 16th
Anaerobic Respiration (without oxygen) makes 2 ATP
Animals do Lactic Acid Fermentation (without oxygen)- makes lactic acid. Lactic acid causes cramps in muscles that have used up their oxygen supply.
Bacteria and Yeast do Alcoholic Fermentation (without oxygen- makes alcohol and carbon dioxide) or Lactic Acid fermentation
Anaerobic respiration takes place in the cytoplasm. Glucose is broken apart to make pyruvic acid. The pyruvic acid is then converted either into lactic acid or ethanol and CO2. It takes 2 ATP for the process to go and makes a total of 4 ATP. The Net Gain is 2 ATP for Anaerobic respiration.
Anthropocene: The current era that we are living in that is marked by human activity such as building roads, burning fossil fuels and deforestation.
Photosynthesis Notes for quiz:
Tropism: Movement of plant towards or away from a stimulus
phototropism- movement towards light
gravitropism- movement away (stem) or towards (roots) the pull of gravity
Parts of a Plant:
Water enters a plant through the ROOTS, travels through the XYLEM on the way to the leaves.
The path of water is soil, roots, stem, leaves.
Carbon Dioxide and Oxygen enter and exit a plant through the STOMATA on the undersides of the leaves.
Sugar is made in the chloroplast in the leaves of a plant. Sugar travels in the PHOLEM throughout the plant.
The transport tissues in plants are the xylem (water) and the pholem for sugar.
Photosynthesis: Done by Producers
6CO2 + 6 H2O (+ light) --> C6H12O6 + 6 O2
Photosynthesis uses light energy, carbon dioxide and water to make sugar and oxygen.
Reactants: Carbon dioxide and water (light needed as energy source)
Products: Sugar and Oxygen
Photosynthesis takes place in the chloroplast of plant cells and some other producers.
Autotrophs/Producers do photosynthesis (Plants, some protists and some bacteria)
The purpose of photosynthesis is to make food (glucose- organic molecule) for the producer.
Sugar that is not used in cellular respiration is used to build the biomass of the plant.
Adding light, or CO2 will increase the rate of photosynthesis in plants. You can measure this by the amount of oxygen bubbles given off in an aquatic plant, or by the growth (biomass) of the plant.
Stages of photosynthesis:
Light Reactions-- Takes place in the Grana in the chloroplast. The Chlorophyll (pigment) uses light to split water and release oxygen. ATP and NADPH is made and used in the Calvin Cycle.
Calvin Cycle-- Takes place in the Stroma of the chloroplast. Sugar is made from CO2 molecules and the H from the water.
Cycles and Energy
Matter (atoms/molecules- such as water, carbon, and nitrogen) Cycles. Energy flows from the sun to producers, to primary consumers and up the food chain.
Abiotic: Nonliving factor...such as gas in the atmosphere, evaporation, precipitation, water, carbon dioxide, nitrogen gas
Biotic: Living factors...photosynthesis from plants, cellular respiration, decomposition, bacteria
Transpiration: Water evaporating from the leaves of plants
Evaporation- Water changing from liquid to gas
Condensation- Water changing from gas to liquid (forms clouds)
Precipitation- Water falling from the sky (in any form)
Runoff- Water moving over the surface of the ground. Plants decrease runoff.
Carbon Dioxide in found as a gas in the air. Carbon molecules make up the backbone of all organic molecules.
Photosynthesis: Takes Carbon Dioxide in the air and changes it into sugar in producers.
Biosynthesis: Organisms use the sugar to build their biomass (make larger molecules to build cells). Biosynthesis creates polymers from monomers. Builds lipids, proteins, carbohydrates and nucleic acids.
Cellular Respiration: Animals/Plants (all organisms) use sugar to make ATP. Carbon Dioxide is released back into the atmosphere
Decomposition: When organisms die the carbon is recycled back into the ground
Burning Fossil Fuels takes carbon that has been stored in the ground and releases it into the atmosphere. This can lead to increased greenhouse gases and global warming.
Nitrogen is found as a gas in the atmosphere. Nitrogen is an important part of living organisms proteins and nucleic acids.
Nitrogen Fixation: Nitrogen is moved from the atmosphere to the soil by Nitrogen Fixing Bacteria in the Root Nodules of Legumes.
Bacteria are important in changing the form of nitrogen in the soil so that they can be used by plants
Denitrification: Bacteria take nitrogen from the soil and release it back into the air as a gas.
Eutrophication: Too much nitrogen in the water (from runoff) can lead to algae blooms. When the algae dies and decomposes the bacteria use all the oxygen in the water and lead to dead zones in the water where nothing can live or grow.
