4
Q

mechanical energy

A

the sum of kinetic and potential energy in an object that does work.

5
Q

Law of thermodynamics

A

Energy cannot be created or destroyed but can be changed from one form to another
-Energy cannot be changed to another without a loss of usable energy

6

21
Q

What happens in the Krebs cycle

A

Series of oxidative reactions occur that produce one ATP and carbon dioxide per turn

Carry out photosynthesis, make their own energy

28
Q

Photosynthesis

A

Convert solar energy into chemical energy

29
Q

Equation of photosynthesis

A

Solar energy + 6CO2 + 6H2O = C6H12O6 + 6O2

30
Q

Are there a lot of pigment chlorophyll

A

There are many pigments of chlorophyll

31
Q

White light

A

The latency is the lightning but all other wavelength lights are being absorbed

32
Q

Stomata

A

33
Q

Chlorophyll

A

36
Q

Grana

A

Stacks of thylakoid

37
Q

Just the light dependent reactions occur

A

In the thylakoid

38
Q

Does this Calvin cycle require light

A

No

39
Q

Tissues

A

Similar cells that perform a common function in the body

40
Q

What are the four types of tissues

A
  • epithelial
  • connective tissue
  • muscle tissue
  • nervous tissue
41
Q

Different classifications of epithelial tissue

A
