Cell membrane
The cell membrane is mostly made up of which type of lipid?
What is Phospholipids?
Diffusion is part of what type of transport?
What is Passive transport
Enzymes are defined as what
What are biological catalysts that help speed up chemical reactions?
What is kinetic energy and name an example.
What is movement energy and motion/walking?
Metabolism is defined as
The sum of all chemical reactions in an organism
What is the fluid mosaic model?
What is Defines the membrane as being a primarily fluid combination of phospholipids, proteins, cholesterol.
What does it mean for a cell to be hypertonic?
Water rushes out of cell, starts to shrink. Higher solute concentration outside cell
Enzymes CHANGE the free energy. True or false
What is false? They do not change free energy
What is the 2nd law of thermodynamics?
What is energy transformations increase entropy and some energy is lost?
In metabolism, macromolecules are broken down and converted into what?
What is ATP or energy?
What type of membrane protein is loosely bounded to the mebrane surface?
What is Peripheral membrane protein?
Define active transport.
Low to high concentrations, energy required, against the gradient.
What are the two types of enzyme activators?
Which reaction is spontaneous, and energy is released?
What is Exergonic?
What is anabolism?
Using energy and building smaller molecules into larger molecules. Synthesis
List at least 3 major functions of membrane protens.
What is transport, enzymatic activity, cell-cell recognition, signal transduction, intercellular joining, attachment to cytoskeleton?
When a plant cell is hypotonic, it is also known as?
What is Turgid?
In feedback inhibition, what happens that stops the production of products?
What is Binding of end product to an enzyme.
List examples of anabolic processes
What is dehydration reactions, photosynthesis, lipid or protein synthesis
Cellular respiration is an example of what type of pathway?
What is Catabolic?
Fluidity of the cell membrane depends on what two factors?
What is cholesterol and phospholipids?
What are the two types of active transport and what do they consist of?
Endocytosis and exocytosis. Under endocytosis, there is phagocytosis, pinocytosis, and receptor mediated.
Enzymes are mostly what type of macromolecule?
What is proteins?
What is Endergonic?
Briefly explain the process of Metabolism, what does it start with, what happens, and what are the end products?
What is first consuming chemical energy or macromolecules, converted to ATP, metabolizes, released as chemical waste in the form of heat, water, or CO2.
