Biology Test 1

Atoms

100

All matter is composed of 1 or more of these tiny particles

Atoms

200

Atoms are made up of protons, neutrons, and this final particle

Electrons

300

Protons and neutrons stick together to make this part of the atom

Nucleus

400

Atoms of the same element have the same number of protons and electrons, but isotopes have a different number of this particle

Neutrons

500

All atoms have a neutral charge in their natural state, but are called this when they lose or gain electrons

Ion

Chemical Rxns

100

This is the force that holds atoms/elements together

Chemical bond

200

This is the area that electrons travel around the nucleus

Energy levels

300

A covalent bond is formed when electrons are THIS

Shared

400

A chemical reaction where energy is released as heat is called this

Exothermic

500

New gas, new liquid, new solid, color change, light produced, or heat produced are signs of this

Chemical reaction/change

Cells

100

This is the basic unit of structure and function in a living organism

Cell

200

Every cell on Earth has this structure

Plasma membrane/cell membrane

300

The plasma membrane helps to maintain normal function for the cell, and normal function of the cell is termed THIS 

Homeostasis

400

This type of cell does not have a nucleus or membrane-bound organelles

Prokaryotic

500

The "head" of the phospholipid likes water because it is THIS

Polar

Organelles

100

This semi-fluid liquid fills the internal environment of the cell

Cytoplasm

200

This is the site of protein synthesis, or where proteins are manufactured

Ribosome

300

This is where the genetic material of the cell is contained, and is not present in prokaryotic cells

Nucleus

400

The site of cellular respiration/ATP synthesis

Mitochondria

500

A series of folded sacs and channels, can be the site of protein and lipid synthesis

Endoplasmic reticulum 

Energy

100

Energy cannot be created or destroyed, only converted in form, is referred to as what

1st Law of Thermodynamics

200

This organic molecule is the end goal for photosynthesis

Glucose/sugar

300

The Calvin cycle is a part of this anabolic process

Photosynthesis

400

C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O is the equation for this catabolic process

Cellular respiration

500

This type of anaerobic respiration takes place in your skeletal muscles after strenuous excercise

Lactic acid fermentation
