Topic 1
They are the fundamental building blocks of all living organisms.
What are cells?
Compounds made up of amino acid.
What are proteins?
Proteins made by living things that speeds up chemical reactions in the body
What are enzymes?
My chemical reaction is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
What is photosynthesis?
The model to describe the structure of the cell membrane.
What is the fluid mosaic model?
Movement of molecules through a cell membrane that requires energy.
What is active transport?
The site of gas exchange in the lungs
What are alveoli?
A process where an enzyme loses its unique three-dimensional shape due to high temperatures and stops working.
What is denaturation?
The organelle where photosynthesis occurs.
What is the chloroplast?
A special tunnel-like protein inside a cell membrane.
What is a protein channel?
Cells with linear DNA.
What are eukaryotic cells?
An enzyme that breaks down starches into simple sugars.
What is amylase?
What is urea?
Alveolar oxygen partial pressure is 13.3 kPa and incoming blood is 5.3 kPa; Predict the movement of oxygen.
What is the movement from alveoli to blood?
A molecule embedded within the phospholipid bilayer of cell membranes that prevents the membrane from becoming too rigid in cold temperatures or too fluid in hot temperatures
What is cholesterol?
The movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.
What is osmosis?
Explains how enzymes work by comparing the enzyme to a lock and its target molecule (substrate) to a key.
What is the lock and key model?
Small network of looping blood capillaries located at the beginning of a nephron that acts as the primary filtering unit of the kidney.
What is the glomerulus?
The digestive system has high ________________ to increase the ability to absorb nutrients.
What is Surface Area?
These membrane molecules have carbohydrate chains attached and act as ID tags or markers for cell-to-cell recognition.
What is a glycoprotein?
The organelle that makes chemical energy through cellular respiration.
What is the mitochondriia?
It is one of the structural features that enhance the function of gaseous exchange surfaces.
What are:
(1) large surface area (2) moist (3) thin (4) surrounded by an extensive capillary system?
It is the section of the nephron that plays a crucial role in the regulation of water in the blood.
What is the Loop of Henle?
The production of 2 ATP molecules during respiration.
What is anaerobic respiration?
This type of passive transport moves molecules across the cell membrane from high to low concentration using transport proteins without using cellular energy
What is facilitated diffusion?
