Unit 1
sum of all chemical reactions that are used to obtain energy and nutrients
What is metabolism?
region of the prokaryotic cytoplasm where the DNA is located
What is the nucleoid?
the process of building larger molecules from smaller molecules with an input of energy
What is anabolism?
The products of mitosis
What are 2, identical diploid daughter cells?
combination of alleles that you inherit from your parents
What is the genotype?
The smallest unit of life
What is the cell?
The eukaryotic cell structure that stores DNA
What is the nucleus?
The site on an enzyme which binds to the substrate
What is the active site?
The state of having 2 sets of chromosomes
Two alleles for a gene segregate during gamete formation
What is Mendel's Law of Segregation?
An educated guess to explain an observation
What is a hypothesis?
Eukaryotic organelle that functions in the synthesis of cell products including lipids, carbohydrates and proteins
What is the endoplasmic reticulum (ER)?
Energy currency of our cells; stores energy in chemical bonds between phosphate groups
What is ATP?
The number of daughter cells produced from meiosis
What is 4?
an individual who has two of the same alleles for a particular gene
What is homozygous?
Type of chemical bond which results from the sharing of electrons between atoms
What is a covalent bond?
Cell structure which functions s a rigid outer barrier which functions in support, protection and the prevention of excess water loss/uptake
What is the cell wall?
A reaction that releases energy
What is endergonic?
Form of cell division which is used for growth, maintenance, and repair
What is mitosis?
your physical appearance or physical expression of your genes
What is phenotype?
The monomer subunit of proteins
What are amino acids?
Main component of the cell membrane
What is the phospholipid bilayer?
the process of breaking down larger molecules into smaller molecules with a release of energy
Form of cell division which is used to produce gametes
What is meiosis?
an allele which is expressed only in the absence of a dominant allele
What is recessive?
