Biomolecules and Enzymes
Provide the body with quick, short-term energy
Carbohydrate
No Nucleus-the DNA/RNA are free floating in the cell
Prokaryotes
Controls what goes into and out of the cell (Semi permeable)
Cell Membrane
he property of a membrane that allows certain molecules and ions to pass through while blocking others. Crucial for cellular homeostasis
Selective Permeability
organisms that cannot synthesize their own food and must rely on consuming other plants, animals, or organic matter for nutrition and energy.
Heterotrophs
Provide long term or stored energy
Lipids
Has a Nucleus (organized DNA/RNA), and membrane bound organelles
Eukaryotes
Is the process of maintaining a “constant state of normal” conditions in the body
Homeostasis
double-layered structure of all cell membranes
Phospholipid Bilayer
organisms that produce their own food by converting inorganic substances into usable energy
Autotrophs
Transport, Storage, antibody, hair, structural support, Enzymes, Messenger,
Protein
Require a living host to survive
Virus
shuts off the original stimulus to return the body to normal.
Negative Feedback
the net, passive movement of particles or molecules from an area of higher concentration to an area of lower concentration
Diffusion
the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy
Photosynthesis
Carry genetic information
Nucleic Acids
when the viral infection replicates Viral DNA destroying the host cell
Lytic cycle
the opposite of negative feedback; it causes a further increase in the response.
Positive Feedback
the spontaneous movement of solvent molecules (like water) through a selectively permeable membrane
Osmosis
specialized organelles in plant and algal cells that conduct photosynthesis,
Chloroplast
Act as a catalyst to control the rate of chemical reactions
Enzymes
when the virus infects a host cell and stays inside
Lysogenic Cycle
a rigid, protective outer layer that surrounds the cell membrane in plants, fungi, algae, and most bacteria
Cell Wall
the energy-requiring process where cells move molecules or ions across a membrane against their concentration gradient (from an area of lower concentration to an area of higher concentration)
Active Transport
The two cycles of Photosynthesis
Light Dependent and Calvin Cycle
