WVU Bio 104 Quiz 2
Cellular Respiration
-Both animals and plants use it to break down sugars (as well as fats and proteins) -The products are carbon dioxide and energy -Animals depend on the energy from it for all their activities -Sugars break down into CO2 and H2O -Depends on oxygen
Pulse
-Each muscular squeeze of the ventricles forces blood through the arteries -We can feel this in our arteries and veins
ATP
-Energy carrying molecule in all living things -Plants use it to build sugar out of carbon dioxide molecules (formed during light reactions)
Photosynthesis
6CO2 + 6H2O + light --> C6H12O6(sugar) + 6O2 Builds sugar out of CO2 and H2O
Accessory Pigments
Aid the plant by absorbing light colors (and energy) that chlorophyll cannot
Proteins
Contain carbon, hydrogen, oxygen, and nitrogen
Atria
Contract and force blood into the ventricles (the right and left atrium abbreviated RA and LA)
Ventricles
Contract and force blood out into arteries (right and left abbreviated RV and LV)
T-wave
Electrical signal indicates atria refilling with blood
P-wave
Electrical signal of the SA indicates contraction of the atria
QRS
Electrical signal of the VA node indicates ventricle contracting
Radial Pulse
Found on the wrist
Sphygmomanometer
Instrument to measure blood pressure
700nm
Long Wavelength Low Frequency
Electrocardiogram (ECG)
Measures electrical activity of the heart
Chlorophyll
Natural solar collectors; collects solar energy and ultimately releases a controlled flow of electrons (electricity) that plants use for energy. (green pigment) -Houses photosynthesis Absorbs energy from sunlight
37 degrees Celsius
Normal core temperature
Calvin Cylcle
Occurs in the stroma Can occur without light as long as ATP is present
70 ml of blood
One beat of your heart circulates approximately this much blood
Hermaphrodite
One individual that produces both eggs and sperm
Systolic Pressure
Pressure in the artery when the heart contracts and pumps blood through the body
Diastolic Pressure
Pressure in the artery when the heart is at rest or being refilled with blood. (the minimum value)
Decomposition
Releases ammonia, water, and carbon dioxide
400nm
Short Wavelength High Frequency
Carotid Pulse
Side of the neck
Metabolism
The combination of all chemical activities (building and breaking down molecules)
Mitochondria
The conversion of sugar into CO2 and H2O and energy occurs in it in the cell
Approximately 390-750nm
The entire spectrum of visible light
Respiration
The exchange of oxygen from external air to the cells within tissues and the removal of carbon dioxide in the opposite direction
After one minute
The hear has pumped about 70 times
Thylakoids
Tiny stacked membrane sacs House thousands of chlorophyll molecules
Vasoconstrict
Too Cold
Vasodilate
Too Hot
120/80mm
Typical blood pressure for a young healthy adult
70-75 beats per minute
Typical resting pulse
Valves
When ventricles contract they slam shut to prevent backflow
