Cellular Respiration/ Photosythesis

Question 1

Cellular Resperation

Answer 1

Glucose + 6O2 + 2ATP = 6CO2 + 6H20 + 38 ATP (gross)

Question 2

Glycolysis

Answer 2

Takes 2 ATPs and breaks down glucose, 2 Pi, and 2NAD+ into 2 Pyruvic acid molecules, 4 ATP, 2 (coenzyme) NADH, and 2H+

Question 3

Glycolysis occurs outside…

Answer 3

of mitochondria

Question 4

Krebs cycle occurs in

Answer 4

Matrix (center) of cell

Question 5

Krebs Cycle (2cd) step

Answer 5

Pyruvic Acid is broken down into CO2, H+, (Coenzyme NADH), and 2 ATPs

Question 6

Cytochromes

Answer 6

The links in ETS made of a protein and Heme (iron group)

Question 7

Electron Transport

Answer 7

Occurs in Cristae (inner edges) of cell. Produces 32 ATP. A process in which the NADH (and FADH2) produced in Glycolysis and Krebs cycle releases electrons to run along a chain of cytochromes in the Cristae of mitochondria which pass the electrons from Heme group to Heme group incrementally storing the energy released by the freed electrons as it goes until the electron finally makes it to the last and lowest energy level cytochrome where it is donated to oxygen to make H2O.

Question 8

Photosynthesis

Answer 8

6CO2 + 6H2O + light energy = glucose + 6Oxygen

Question 9

Photolysis occurs in…

Answer 9

Grana of the chloroplast

Question 10

Photolysis (equation)

Answer 10

PHOTONS + WATER = HYDROGEN (contained in H acceptor) + OXYGEN + ATP

Question 11

Dark reaction occurs in the…

Answer 11

Stroma of the Chloroplast

Question 12

Dark reaction (CO2 Fixation) Equation:

Answer 12

ATP + 6CO2 + H = GLUCOSE

Question 13

Anaerobic Respiration:

Answer 13

Also called fermentation, skips Krebs Cycle and turns Pyruvic Acid into end products (such as lactic acid or alcohol) and CO2. Not as efficient as Aerobic Respiration.

Question 14

NADH=

Answer 14

2 electrons + 1 proton + NAD+
