Cellular respiration

Question 1

What is the goal of Cellular respiration?

Answer 1

Break bonds of glucose to get energy using oxidation

Question 2

What is the ATP structure?

Answer 2

Two adenine nitrogen bases, Ribulose connects to adenine to form adenosine which connects to 3 phosphates making the triphosphate (ADENOSINE TRIPHOSPHATE!!)

Question 3

How is ATP such a good energy carrier?

Answer 3

Since phosphate groups are negative, they form repulsion which makes them unstable, and when they are broken the repulsion is reduces and a mass amount of energy is released which is transferred to the molecules for cells.

Question 4

Autotroph vs Heterotroph

Answer 4

Autotrophs make their own food through photosynthesis, and does cellular respiration

Heterotrophs ingest food and does cellular respiration

Question 5

Formula for cellular Respiration

Answer 5

C6H12O6+6O2->6CO2+6H2O+ATP

Question 6

Diff. between photosynthesis and Cellular respiration

Answer 6

They have different raw materials (Ph- CO2 and water and CR- Glucose and O2)

Diff. products- Ph produces Glucose and O2 and Cellular produces CO2 and Water

Ph occurs only in the day and Cr occurs day and night

Ph occurs in organisms with chlorophyll and Cr occurs in all organisms (mitochondria containing)
Ph- Synthesis/endergonic and Anabolic and Cr is breakdown/exergonic/Catabolic

Question 7

3 types of Phosphorylation

Answer 7

PHOTOphosphorylation
Substrate level phosphorylation
oxidative phosphorylation

Question 8

What is Aerobic respiration?

Answer 8

Occurs with oxygen, that produces efficient amounts of ATP (36-38), and oxidative, and substrate level phosphorylation are Aerobic. Utilize substrate-level oxidation and oxidative phosphorylation

Question 9

What’s Anaerobic Respiration?

Answer 9

Doesn’t use oxygen, less efficient (like only 2 ATP) and only occurs in Cytoplasm w/no organelles.

Question 10

What is substrate level phosphorylation?

Answer 10

Takes p-group from organic intermediate molecule and adds it to ADP to make ATP, and only makes a net gain of 2 ATP (in glycolysis and anaerobic.)

Question 11

Oxidative level phosphorylation

Answer 11

Could make a lot of ATP, it Aerobic and uses the combo of the ETC and ATP synthase complex to make ATP

Question 12

Photophosphorylation

Answer 12

Uses light energy to form ATP is photosynthesis

Question 13

What is alcohol fermentation in Yeast and Bacteria?

Answer 13

Glucose is split, then Carbon dioxide gets released, and NADH gets oxidized into NAD+ and the end products are a net gain of 2 ATP and alcohol.

Question 14

What is lactic acid fermentation in muscle cells?

Answer 14

If there is a lack of oxygen, a cramp build up of lactic acid slows you down and allows muscles to survive w/o oxygen for a period of time.

Glucose gets split, NADPH gets oxidized into NAP+ and the end product is two ATP and lactic acid.
