Catabolism - chemical reactions takes large molecules
and makes them smaller, releasing energy in the
process (exothermic)
The codon encoding for the first amino acid added
during translation is AUG
Lysosomes contain digestive enzymes used to digest pathogens and
other chemicals the cell is looking to get rid of.
In which part of the cell is glucose fully broken down to
release energy as ATP – mitochondria.
In which double-membraned organelle does DNA
replication occur - nucleus
Metaphase - phase of mitosis do the chromatids line up
in the middle?
Define:
Anaphase
Telophase
Metaphase
Prophase
Interphase
What is the resulting product of meiosis - two haploid cells
Ribosome - the organelle that is directly involved in
protein synthesis.
Identify this membranous structure depicted in the
image below with the black arrow.

, Rough Endoplasmic Reticulum
Peripheral Proteins are on the outside of a cell
membrane and acts as cell identity markers.
The use of a carrier protein to move a chemical, like an
amino acid, across a membrane from an area of high
concentration to an area of low concentration, in the
absence of energy is an example
of facilitated diffusion
Cells with a high regenerative capacity undergo mitosis
at a more frequent rate
Endocrine glands are mainly composed of epithelial tissue
Skeletal muscle tissue types has alternating dark and
light bands and is under conscious (voluntary) control
Main tissue type shown
Epithelial tissue
Nerve cell body - Soma
Cells of this tissue type have specialized junctions that
allow for the rapid spread of electrical impulses. Cardiac
muscle
Examples of passive membrane transport:
Facilitated
