Q

Mitochondria

A

An organelle in both plant and animal cells that is the location of the cellular respiration reaction. Glycolysis takes place in the cytoplasm very close to a mitochondrion. The Kreb’s Cycle occurs inside the mitochondria, and the Electron Transport Chain occurs inside the mitochondria.

Q

Xylem & Phloem

A

These are tubes inside plants that function much like the veins, arteries, and capillaries in mammals. They move water and solid substances throughout the plant so that all cells are supplied with the substances they need to live.

Q

Atmospheric air

A

A mixture comprised of 10 gases in varying amounts: Nitrogen makes up 78%. Oxygen makes up 21%. Argon makes up less that 1%. Carbon dioxide makes up about 0.04%, and all other components exist in only trace amounts less that 0.03%. Air is the source of both C02 and 02 used in life process reactions.

Q

Catabolic

A

reaction that breaks down sugars

24
Q

Anabolic

A

reaction that produces sugars

25
Q

aerobic

A

In the presence of Oxygen (O2)

26
Q

anerobic

A

In the absence of Oxygen (O2)

27
Q

Fermentation

A

The formation of alcohol from carbohydrates (sugars) when oxygen is not present. Fermentation results in some ATP formation, but is less efficient than aerobic respiration.

28
Q

Glycolisis

A

The first stage of cellular respiration in which 2 units of ATP are produced.

29
Q

Krebs (cirtic acid) cycle

A

The middle stage of cellular respiration during which 2 units of ATP are produced.

30
Q

Electron transport

A

The final stage of cellular respiration during which 30 — 34 units of ATP are produced.

31
Q

autotroph

A

Organism capable of making its own food

32
Q

heterotroph

A

organism incapable of preforming photosynthesis, therefore it eats other organisms

33
Q

mesophyll

A

middle layers of cells in a leaf

34
Q

granum

A

stack of thylakoids in a chloroplast

35
Q

photoautotroph

A

an organism capable of synthesizing its own food using the
energy of light

36
Q

stroma

A

fluid filled space around the grana in a chloroplast where the
calvin cycle reactions of photosynthesis take place

37
Q

thylakoid

A

disk shaped membranous structure inside a chloroplast
where the light dependent reactions of photosynthesis take
place using chlorophyll embedded in the membranes
