Respiration
|
Process of breaking down glucose to releasing energy.
It is definitely not breathing! |
|
|
Glucose + Oxygen > Carbon dioxide + ______ (+_____)
|
Water(+energy).
These reactions always look more complicated than they are. Simple - Glucose and oxygen under the right circumstances can give water and energy, and carbon dioxide. |
|
|
Diffusion
|
Movement of particles from an area of HIGH concentration to an area of LOW concentration.
(Steps DOWN the concentration gradient) (One room to full, so I'll move into the next room) |
|
|
How does glucose move from blood to cells
|
Via diffusion, there is more glucose in the blood than the cells so it moves where there is more room, DOWN the concentration gradient.
-Understand this as it is applied in many other situations in science. |
|
|
Briefly describe what happens when you exercise
|
Answer should include:
Increased respiration Increased breathing rate Increased heart rate Understand the purpose of each change |
|
|
Cardiac output = ____ ____ x ____ _____.
|
Heart rate x stroke volume
(How fast x how much) |
|
|
Anaerobic respiration
|
Respiration without oxygen
Glucose > Lactic acid (+ energy) |
|
|
EPOC
|
Excess post-exercise consumption
|
|
|
Photosynthesis reaction
|
CO2 + H2O >(Sunlight and chlorophyll)> glucose + oxygen.
(Not as complicated as it looks) |
|
|
Photosynthesis
|
The process that produces energy in plants
|
|
|
3 things that affect the rate of photosynthesis
|
1. Light
2. CO2 3. Temperature |
|
|
Osmosis
|
The movement of water across a partially permeable membrane, from a region of high water concentration to a region of low water concentration.
This works well because water molecules are very small. Again, it moves DOWN the concentration gradient. |

How do root hairs take in water?
|
Osmosis

|
|
How do root hairs take in minerals?
|
Active transport
|
|
|
Quadrat
|
A square frame enclosing a known area. Used to study distribution of organisms.
|
|
|
Which releases more energy, aerobic or anaerobic respiration?
|
Aerobic
|
|
|
Another name for CO2
|
Carbon dioxide
