5.Cellular Respiration and Photosynthesis

Question 1

Cells and energy

Answer 1

cells require chemical energy for all activities
store immediately usable chemical energy in the form of ATP
atp molecule high energy terminal phosphate bond broken easily release small packets of energy to carry out cellular work
once ATP is given up its charge becomes adp and pi is recharged and used again

Question 2

cellular respiration

Answer 2

process produce energy breaking down organic molecules using glucose and oxygen

Question 3

aerobic respiration

Answer 3

in cytosol and mitrochondria if 02 is present
glycolysis, krebs (mitrochondrial matrix) and electron transport chain

Question 4

cellular respiration summary balanced chemical equation

Answer 4

C6H1206 + 6O2 -> 6Co2 + 6H2O + energy 30 or 32 ATP (some heat)

Question 5

anaerobic cellular respiration

Answer 5

aka fermentation occurs when there is no oxygen present
only occurs in cytosol
produces only 2 ATP
builds up lactate acid in aniamls
results in production of ethanol and CO2 in plants and yeast

Question 6

photosynthesis

Answer 6

process where chlorophyll and light energy turn carbon dioxide and water into chemical energy in the form of glucose
occurs in two stages light dependent and light independent
carbon dioxide and water -> oxygen and glucose and water

Question 7

parts of the chloroplasts
