1

Explain the flow of energy in biology with regard to cellular respiration and the sun

sun is source of nearly all energy used by living organisms

2

Explain the flow of energy in biology with regard to cellular respiration and photosynthesis

captures energy from light used in anabolic reactions to build large/ complex organic molecules

3

Explain the flow of energy in biology with regard to cellular respiration and catabolism

in catabolism cellular respiration /fermentation breaks down large/complex organic molecules to provide energy to the cell

4

name the types of carbohydrate catabolism

cellular respiration and fermentation

5

cellular respiration in carbohydrate catabolism

lots of ATP/glucose broken down
requires glucose and O2

6

fermentation in carbohydrate catabolism

little bit of ATP/ glucose broken down
requires glucose

7

name the cellular respiration chemical reaction

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

8

What involved in the cellular respiration process

glycolysis, citric acid cycle, oxidative phosphorylation

9

describe and tell where the items that contribute to cellular respiration

1. glycolysys is described as glucose 6c -----> 2x Pyuvate (3c) and is located in the cytoplasm
2. citric acid cycle description is 2x pyruvated 3c ---> 2x acetyl-CoA ---> 6CO2 and is located in the mitochondria matrix
3. oxidative phophorylation description- electrons carries electrons from glucose and drop off at ox phis-energy used to ATP and is located in the mitochondrial membrane

10

describe glycolysis energy and investment

Energy Glucose (6C)
Investment I 2 ATP ----> 2 ADP + P
------------------------------------------------------------------------------------
Payofff /\ 4ADP+P ---> 4 ATP
/\ 2 NAD+ + H6 ----> NADH
Pyruvate Pyruvate
(3C) (3C)

11

describe decarboxylation

(Glycolysis) (Glycolysis)
Pyruvate (3C) Pyruvate 2NAD+ + H+-->2NADH

I I
ACETYL-CoA ACETYL-CoA
(2c) (2c)

12

describe citric acid cycle

acetyl-CoA 1 cycle and acetyl-CoA Cycle
6NAD+ H+ ---> 6NADH
2FAD +2H+ --->FADH
2ADP+p---> 2ATP

13

What are the two ways of oxidative phosphorylation use

electron transport chain and chemiosmosis

14

uses the energy from electrons in the form of glucose to make a H+ gradient

electron transport chain

15

consists of proteins embedded in the inner mitochondrial membrane

electron transport chain

16

H+ gradient moves back across the membrane

chemiosmosis

17

used by ATP synthase to convert
ADP+ P --->ATP

chemiosmosis

18

32-34 ATP made per glucose

chemiosmosis

19

Name the three phases of Aerobic respiration ATP

glycolysis, citric acid, oxidative phosphorylarion

20

how is glycolysis involved in Aerobic respiration ATP

involves 2 ATP (4ATP - 2ATP used)

21

how is the citric acid cycle involved in Aerobic respiration ATP

involves 2 ATP

22

how is oxidative phosphorylation involved in Aerobic respiration ATP

involves 32-.34 ATP and 36-38 ATP per glucose

23

What are the 2 process involved in Fermentation

glycolysis and secondary reactions (ethanol/lactic acid fermentation

24

How is glycolysis involved in fermentation

the same as glycolysis from cellular respiration
-the only fermentation that produces ATP
-2 net ATP per input glucose -converts 2NAD+ ----> 2 NADH

25

How is secondary fermentation (Ethanol/lactic fermentation) involved in fermentation.

it converts NADH back to NAD+ that can be used to do more glycolysis

26

how is other molecules involved in fermentation

they enter into those cellular respiration cycles based on their structure and produce different amount of ATP backed on where they enter cellular respiration

27

how can many other cells do fermation

through the cytoplasm glycolysis with glucose and pyruvate
from pyruvate with O2 cells in the mitochrdria decarboxlatiom the use the citric cycle and the oxidative phosphorylation, with no O2 cells use the cytoplasm with latic acid and fermentation

28

What is the plant's general structure

body plan, root, shoot

29

what is the function of the root and where is it located

the function of the root is to absorb water and mineral and it hold the plant up. It is located under ground

30

what is the function of the shoot and where is it located?

the function of the shoot is photosynthesis and reproduction. It is located above ground
