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
