Q

What energy is released when the chemical bonds of glucose are broken?

A

Chemical energy in form of ATP

24
Q

What does diffusion use?

A

Gasses

25
Q

What does osmosis do

A

Move water from high concentration to low concentration

26
Q

What does facilitated diffusion use

A

Protiens, channel ions, carriers, glucose

27
Q

What are the two types of endo cytosis?

A

Phagocytosis(eat), and pinocytosis(drink)

28
Q

Gas and water exchange occur where?

A

The stomata

29
Q

What does the mitochondria generate?

A

ATP energy

30
Q

What is ATP?

A

the source of energy for use and storage at the cellular level

31
Q

Where is the site of photosynthesis?

A

Autotrophs

32
Q

Where are chloroplasts found?

A

Palisade and spongy tissue and in gaurd cells

33
Q

What is around chloroplasts?

A

A double membrane to control movement between chloroplast and the cytoplasm

34
Q

What are chloroplasts filled with?

A

Fluid called stroma where carbohydrates are made

35
Q

Where is the site of cellular respiration?

A

Mitochondria

36
Q

What are the mitochondria surrounded by?

A

Flat outer membrane and a folded inner membrane. Folds are called cristae and increase the surface area available for making atp

37
Q

What is mitochondria filled with?

A

Fluid called matrix

38
Q

Formula for photosynthesis?

A

Light energy+ 6Co2+ 6H2O= C6 H12 O6 + 6o2

39
Q

Formula for cellular respiration?

A

C6 H12 O6 + 6o2=6co2+ 6 H2O + ATP(36-38)

40
Q

What is a metabolic pathway?

A

Step by step series of enzyme controlled reactions in a cell.

41
Q

What is metabolism?

A

All the reactions within a cell to support or sustain life

42
Q

What are anabolic reactions?

A

They use energy to make large molecules from smaller ones

43
Q

What is a catabolic reaction?

A

Releases energy by breaking large molecules into smaller ones

44
Q

What speeds up anabolic and catabolic reactions?

A

Enzymes are used because they lower the amount of energy needed for the reaction to start

45
Q

What is oxidation?

A

When an atom or molecule loses an electron

46
Q

What is reduction?

A

When an atom or molecule gains an electron

47
Q

Reduced molecules with large amounts of energy have what?

A

Reducing power

48
Q

What are thylakoid pigments?

A

Molecules that absorb and reflects some wave flanks of light

49
Q

Plants appear to be green, because?

A

It is being reflected by the chlorophyl

50
Q

What does cellular respiration do?

A

Breaks down glucose into useable energy for the cell

51
Q

What does cellular respiration use? (intermediate products)

A

ATP, FADH2 NADH

52
Q

What are the three methods of releasing energy?

A

Aerobic, anaerobic, fermentation

53
Q

What is the kreb cycle?

A

An aerobic process within the mitochondrial matrix

54
Q

Where does pyruvate move?

A

To the matrix of the mitochondria

55
Q

What does pyruvate lose and what does it form?

A

Loses a carbon, and it forms CO2

56
Q

What is the purpose of the Krebs cycle?

A

To transform the energy from pyruvate into reducing power of NADH and FADH2
