Characteristics
Condition in which an organism maintains a stable internal environment
Homeostasis
Smallest particle of an element that still has properties of that element
Atom
Sharing of electrons between two atoms that holds the atoms together
Chemical Bond
Sum of all of an organism’s biochemical reactions is called
Metabolism
Products of Cellular Respiration
Carbon Dioxide and water
Producers use sunlight for energy to produce their own “food.” The process is called
Photosynthesis
Any carbon based compound in living things includes classes such as carbohydrates, proteins, lipids and nucleic acids
Biochemical Compound
Class of Biochemical compounds that includes DNA and RNA
Nucleic Acid
Proteins that increase the rate of biochemical reactions
Enzymes
Cellular Respiration takes place in the
Mitochondria
The reaction a stimulus produces is called
a response
Polymers are large molecules that consist of many smaller, repeating molecules, called
Monomers
Monomers of proteins
Amino acids
Larger molecules break down to form smaller ones
Catabolic reactions
The products of photosynthesis are
Oxygen and glucose
Basic units of structure and function of living organisms.
Cells
The nucleus is surrounded by negatively charged particles called
Electrons
Nucleic acids consist of chains of small molecules called
Nucleotides
Biochemical reactions of metabolism can be divided into two general categories
catabolic reactions and anabolic reactions
What together provides energy to almost all living cells
Photosynthesis and cellular respiration
Five characteristics that defines living things
1. made of one or more cells
2. need energy to stay alive
3. respond to stimuli in their environment
4.grow and reproduce
5. maintain a stable internal environment
Phospholipids contain the element
Phosphorus
Four nitrogen-containing bases in DNA
adenine, thymine, guanine, and cytosine
The instructions are encoded in the sequence of what bases in DNA’s nucleotide chains
Nitrogen bases
Energy produced from Cellular Respiration
ATP
