what molecule does amylase make from starch?
What is used to detect starch?
what is it called when the temperature is so high the enzyme becomes inactive?
the degradation of a large, often insoluble molecule into components that can enter into respiration or be reassembled into other compounds
what does complex carbohydrates yield when digested?
what does proteins yield when digested?
what does lipids yield when digested?

what does starch yield when digested?
What test detects maltose and glucose?
the cellular processes that release energy from a food source such as glucose
the removal of hydrogens from glucose is
what plays a large part in determining how much of the food's energy is trasferred to ATP?
the recipient of electrons
the electron transfers that yield most of the energy captured in ATP occur in the
cristae of the mitochondria
what is the process that plants carry out in the absence of molecular oxygen?
whats the common end product of fermentation in plants?
the potential ATP yield of respiration is almost ___ times greater when oxygen is present
the experiment with 5 bottles that removed air and showed that germination forms Barium Carbonate
heat is released during all respiration and represent food energy that is not captured by
what did the fermentation tubes contain

most living organisms function either as_____or_____
plants that are green and can make their own food
an organism that makes its own food is known as
an autotroph (self-feeder)
an organism that that consumes others food
cytoplasm, but outside the vauole
have well developed thylakoid membrane system and contain chlorophyll
where does the absorption of light and energy transfer in the chloroplast?
where does the incorporation of electrons into ATP and NADPH+H+ occur?
grana of chloroplast
where does the synthesis of sugars and amino acids occur?
functions of photosyntesis products
* power the plants activites
* produce cell structure
* be exported to other parts of the plant
* stored in place for reuse later
the name of the process of keeping seeds growing in an environment without oxygen
what was used to test for enzyme activity's and digestion?
what was used to test respiration?
Barium Hydroxide solution

chlorophyll a and b
an instrument containing a prism that separates wite light into the component colors
What determines the percent transmission of light by a pigment chosen from those used before
what do dark zones represent in the spectroscope?
light absorption by the pigments
refers to the light that passes through a sample because it is not absorbed by the pigment
the light that the pigment takes up
what machine is used to measure light transmission and absorption?
what is the dim light you see coming from the tube?
