Flashcards in UNIT 3 Energy Transformation Deck (43):
1

It is defined as the capcity to do work

Energy

2

ATP

Adenosine Triphosphate

3

The energy released from the breakdown of food and transfwrred in molecules

ATP ( Adenosine Triphosphate)

4

A double ring of carbon and nitrogen atoms

Adenine

5

ADP

Adenisine Diphosphate

6

NAD

Nictinamide Adnenin Dinucleotide

7

NADP

Nictonamide Adenine Dinucleotide Phosphate

8

FAS

Flavin Dinucleotide

9

Both molecules have a nitrogen- containing ring celled

Nicotinic Acid

10

In FAD, the chemically active Portion

Flavin Group

11

The removal of electrons or protons coenzymes

Oxidation

12

Addition of electrons to a molecule

Reduction

13

The chemical reactions performed by the coenzymes

Oxidatition-reduction reactions

14

It is the ability to do work or to produce changes in matter

Energy

15

It is a very viral process on which almost all living things depend, either directly or indirectly. Comes from the loght of the sun.

Photosynthesis

16

He is a flemish botanist the first who studied photosynthesis in 1630

Jonvan Helmont (1580-1644)

17

In 1772, showed that a spring of mint would “restore” air that had been “injured” by a burning candle

Joseph Priestley (1733-1804)

18

Supported the findings of priestley, and added that this air (oxygen) could only be restoeed by plants if the sun was shinning

Jan Ingenhouz (1730-1799)

19

Weighed both the air and the plant before and after phtosynthesis

Nicholas de Saussure (1767, 1845)

20

In 1930s, of standford University was able to prove that light splits water, prducing oxygen

C.B. Van Niel (1897-1985)

21

Plants Phtosynthesis: an overview

Heterotrophs
Autotrophs

22

Other eating, cannot synthesize their own food and depend on autotrophs and other organisms for their substance

Heterotrophs (other eating)

23

Self-feeding, Synthesize their own food

Autotrophs

24

Autorophic organisms are of two main types

Photoautotrophs
Chemosutotrophs

25

Which include green plants and purole bacteria and can utilize light energy to synthesize organic molecules

Photoautotrophs

26

Which includes some bacteria that can synthesize organic substances from the inorganic substances in their environment and are not dependent on light energy

Chemoautotrophs

27

Involve the stable transfer of electrons netween atoms

Oxidation reduction or Redox reaction

28

An atom or molecules is said to be REDUCED when it GAINS one or more electrons

.

29

When it LOSES on or more electrons it is OXIDIZED

.

30

Are the mahir site of phtosynthesis in green plants

Leaves

31

Are abundant in the leafs mesophyll layer

Chloroplasts

32

The layer next to the outer surface layer of the cells

Epidermis

33

Is a form of electromagnetic (em) radiation which is a wave that has electric and magnetic components

Light

34

Light also has a particle like quality consisting of diescrete particles

Protons

35

It is the mahor photosynthetic pogment

Chlorophyll

36

The other phtosynthetic pigments

Accessory Pigments

37

Hundred of theses pigments are organize into light collecting units

Photosynstems

38

Energy carrier

adenosine Triphosphate (atp)

39

Is bonded to rubise to form a unit

adenosine

40

This process is termed Dephosphorylation

Dephosphrylation

41

It is catalyzed bu he enzyme

At Phase

42

After dephosphorylation, two phosphate groups and adenosine remain dormint the compund

Adenosine Diphosphate or ADP

43

The process is generally refered as?

Phosphorylation
