Yeast is a type of _________
Fungus
What is the word that describes C6H12O6
Glucose
What molecules does fruit represent?
Glucose
What does starch do for a plant?
It stores energy
What are chloroplasts?
It's where photosynthesis takes place, it contains chlorophyll
What compound is responsible for the cramps that we feel when we run out of oxygen?
Lactic acid
How does cellular respiration work?
Living cells obtain the products of photosynthesis (sugar molecules) and undergo cellular respiration to produce ATP molecules
What are the reactants in respiration
Oxygen and glucose
How is ADP formed?
When the Hydrogen bond breaks between the second and third phosphate groups.
Do all plants have a mitochondria?
Yes
What are the reactants in photosynthesis
carbon dioxide and water
What are the products in cellular respiration?
carbon dioxide, water, and ATP
What are the products of photosynthesis?
glucose and oxygen
Fermentation is a metabolic process that coverts
sugar into acids
___________ is a type of Chemical Energy that Releases energy when the chemical bonds are broken between two phosphate groups.
ATP
What is the fermentation equation?
C6H12O6 → 2 C2H5OH + 2 CO
What are pores in a plant's skin called?
stomata
What does an ATP molecule look like
1 adenosine unit linked in with 3 phosphate units
29. How many ATP molecules are produced in one reaction during cell respiration
38
What percentage of the food we eat comes from carbohydrates?
60%
What is the reaction for photosynthesis?
6CO2 + 6H2O + light energy= C6H12O6 + 6O2.
What is chlorophyll?
A green pigment found in the chloroplasts of plants, algae, and some bacteria. It absorb light from the sun through the chlorophyll pigment and using water and carbon dioxide obtained from the environment, undergo a series of chemical reactions to produce carbohydrate molecules.
What is the reaction for chemical respiration?
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
What does ATP stand for and what is it?
Adenosine Triphosphate It is an energy molecule It is a nucleotide
What is more efficient? - Anaerobic or Aerobic Respiration?
Aerobic
Is yeast fermentation an anaerobic or aerobic form of cellular respiration? Why?
Anaerobic because it does not need oxygen to complete cellular respiration.
_______ is the process used by plant cells to convert light from the sun into chemical energy, so as to create energy-rich glucose molecules like glucose.
Photosynthesis
Cellular respiration takes place in _______ and __________
Plants and Animals
What is the difference between respiration and breathing?
RESPIRATION IS A CHEMICAL REACTION
What is the name of the length of time needed for us to pay back our oxygen debt?
Recovery time
What is anearobic respiration?
Respiration without using oxygen
How is ADP made into ATP?
The ADP enters the cell's mitochondria and is recharged when the mitochondria adds another phosphate to the molecule. The molecule becomes ATP again.
ATP is a molecule in the cell that allows for quick and easy ____________ when the organelles need it
access to energy
What does ADP stand for?
adenosine diphosphate
How is ATP like dollars
its a common currency
The build up of lactic acid causes:
muscle fatigue/ aching
What is aerobic respiration?
respiration with using oxygen
What does fermentation occur in?
yeast, bacteria, and other microorganisms, as well as oxygen starved muscle cells
