Chapter 03-Cell Processes Flashcards
How are elements arranged on the periodic table?
by their properties
Where are the metals located on the periodic table?
on the left (and middle)
Where are the non-metals located on the periodic table?
on the right
What happens to the atomic number as you move from left to right across the periodic table?
it increases
Atom
smallest particle of matter that still has chemical properties of the element
Molecule
combination of two or more atoms
Element
Substance that cannot be broken down into simpler substances
Compound
combination of two or more elements
Chemical Bonds
join atoms together in a molecule
Chemical Equation
describes a chemical reaction. Starting materials on the left, end products on the right.
Endothermic
stores energy
Exothermic
releases energy
Carbohydrates
starches and sugars, major source of energy
Lipids
fats, oils and waxes. make up cell membrane
Proteins
make up muscles, antibodies, enzymes
Nucleic Acids
DNA and RNA
Water
Makes up almost 70% of our body
Chemical Reactions happen in water
Glucose
sugar that all organisms use for energy
Photosynthesis - location
chloroplast
Photosynthesis - starting materials
sun’s energy, water, carbon dioxide
Photosynthesis - end products
glucose and oxygen
Which living things perform photosynthesis?
Plants, Algae, some bacteria
Cellular Respiration - location
mitochondria
Cellular Respiration - starting materials
glucose and oxygen
Cellular Respiration - end products
water, carbon dioxide and energy (ATP)
Which living things perform cellular respiration?
Plants and animals
Process that stores energy
Photosynthesis
Processes that release energy
Cellular Respiration
Alcoholic Fermentation
Lactic Acid Fermentation
Alcoholic Fermentation - location
cytoplasm
Alcoholic Fermentation - starting material
glucose
Alcoholic Fermentation - end products
carbon dioxide, alcohol and energy (ATP)
Which living things perform alcoholic fermentation?
yeast
Lactic Acid Fermentation - location
cytoplasm
Lactic Acid Fermentation - starting material
glucose
Lactic Acid Fermentation - end products
lactic acid and energy (ATP)
Which living things perform lactic acid fermentation?
our muscle cells, some bacteria
