|
What are the characteristics of living things? MSGREN? |
Metabolism, Sensitivity, Growth, Reproduction, Excretion, Nutrition. |
|
|
What is the word and chemical equation for respiration? |
Glucose + oxygen ---> carbon dioxide + water + ENERGY
C6H12O6 + 6O2 ---> 6CO2 + 6H2O + ENERGY |
|
|
Define cellular respiration. |
The controlled release of energy by organic compounds to produce ATP. |
|
|
In humans, what is the source of the organic compounds broken down for cellular respiration? |
food eaten. |
|
|
How do plants get the organic compounds needed for cellular respiration? |
make it themselves by photosynthesis. |
|
|
How is ATP produced? |
if a phosphate group is linked to a adenosine diphosphate (ADP). |
|
|
Why is cellular respiration essential for an organism? |
Because each cell needs a continuous supply of ATP but ATP cannot travel through plasma membranes and cell respiration releases energy from organic compounds in orde to make ATP, this is why cell respiration is essential. |
|
|
Is ATP from cell respiration immediately ready to be used in the cell, or does it take a while before the ATP can be used? |
immediately, because cell respiration happens inside the cell. |
|
|
Name three types of activities in which cell require energy. |
1. synthesizing large molecules (DNA, proteins) 2. pumping molecules across membranes by active transport. 3. moving things around the cell (chromosomes, vesicles) |
|
|
Why do cells require a continuous supply of ATP for cell activities? |
because after it is used in a cell it is converted into heat and cannot be reused but is lost to the environment. |
|
|
say which one is true about anaerobic respiration:
least efficient or most efficient produces 3 molecules of ATP or 2 molecules happens with or without oxygen
|
least 2 without |
|
|
Name the three situations in which anaerobic respiration is used. |
1. for a short but rapid burst of ATP production is needed. 2. when oxygen supplies run out. 3. in environments with a low oxygen concentration in the air. |
|
|
In humans, glucose is converted into ________ through anaerobic respiration.
What acid is the blank? |
lactic acid. |
|
|
In yeast and plants, glucose is converted into _______and_______ through anaerobic respiration.
what substance and gas are the blanks?
|
ethanol and carbon dioxide. |
|
|
Name three properties of yeast, that give it an advantage in baking. |
1. unicellular fungus. 2. creates bubbles in a substance. 3. can respire aerobically or anaerobically.
|
|
|
Anaerobic respiration involves the production of what acid that can only be temporarily tolerated? |
lactate |
|
|
Aerobic cell respiration produce what compounds? |
CO2 and H2O (water) |
|
|
In eukaryotes, in which organelle of the cell does most aerobic respiration happen? |
mitochondria. |
|
|
There is no mitochondria present in prokaryotes, but what is the equivalent of a mitochondria in prokaryotes? |
lysosomes. |
|
|
What is the word equation for the chemical reaction in the mitochondria? |
glucose + oxygen ----> carbon dioxide + water
