Definition |
Protein |
A macromolecule in living things that is made of chains of amino acids subnuits. |
Carbohydrate |
A type of carbon-based molecule in living things. |
Nucleic Acid |
One of several carbon-based molecules that carry an organism's genetic code. |
Protein |
Control the chemical activity of a cell and support growth and repair. |
Carbohydrates |
Include sugars and starches used for energy or as structural materials. |
Composed |
made up of, put together in form, ex: all living things are ______ of cells. |
Carbohydrate |
molecules contain carbon, hydrogen and oxygen |
Energy |
can come by means of food-sun, glucose (sugar), carbohydrates. Helps us to do things. |
Cellular Respiration |
A process in which cells use oxygen to release energy stored in sugars. |
Fermentation |
A chemical process by which cells release energy from sugar when no oxygen is present. |
Herbicide |
Effects, Kills, Damages: like vinegar on plants |
Glucose |
A sugar molecule that is a major energy source for most cells, produced by the process of photosynthesis. |
Solvent |
The part that dissolves something. |
Solute |
The material that is getting dissolved. |
Solution |
the outcome of two different items put together |
Sustain |
to keep in existence; maintain or prolong, to meet the current needs without compromising the future needs of something. |
Repel |
to keep away, stay away. Like lipid tails stay away from water. |
Animal Cells |
has mitosis phase and centrioles |
Plant Cells |
has mitosis phase but no centriole |
46; 23 |
Every human has ___________chromosomes or ______amount of pairs |
Passive |
During_____________transport, substances are moved from areas of low concentration to high concentration |
Active |
In order for the process of passive transport to occur the cell must supply an energy source called_____________ |
Large; Endocystosis |
If particles that are too ________pass easily through the membrane it can enter a cell by a process called __________. |
Exocytosis |
Large particles can leave a cell by the process called________. |
Osmosis |
The diffusion of water through a membrane |
Cell Membrane |
Materials move in and out of a cell by passing through the_________________. It allows some materials to pass but prevents others. |
Water, Waste |
A cell only survives if ______________is taken into the cell and _______________ are taken out. |
Thermal Radiation |
is the release (diffusion) of heat into the air. Ex: visible light |
Diffusion (mixing) |
the constant random motion of molecules from an area of high concentration to low concentration |
Gradient |
Is the difference in concentration (cell membrane could be one). During diffusion molecules like to move down the __________. |
Gas, Liquid, and Solid |
Diffusion happens in 3 states:______,_______,_______ |
Gas |
Diffusion happens the fastest in this state |
Solid |
Slowest moving diffusion. Vibrates- doesn't move a lot |
Liquid |
The 2nd fastest diffusion |
Temperature |
Rate of Diffusion: 1 |
Size of Molecule |
Rate of Diffusion: 2 |
Steepness Gradient |
Rate of Diffusion: 3 |
ATP |
Energy made from glucose and oxygen |
Carbohydrates, Lipids, Protein, Nucleic Acids |
4 types of Large Molecules |
Water |
A ________ molecule, consists of two hydrogen atoms and one oxygen atom |
Polar |
A water molecule is also a ____________molecule |
Lipids |
Fats, Oils, Waxes found in living things. |
Membrane; water |
Cell_______are composed of special lipids that have one end that _____water. |
