cell shrivels

23
Q

heme means

24
Q

lyse means

25
Q

Hemolysis is

A

the process by which red blood cells break down and release their contents into the surrounding fluid.

26
Q

Turgor pressure

A

the force that pushes the plasma membrane of a cell against its cell wall

27
Q

red bloods cells do what in a hypertonic solution

28
Q

plant cells in a hypertonic solution

A

plasmolysis

29
Q

energy is what?

A

the ability to do work or bring about a change

30
Q

Kinetic energy is

A

energy in motion

31
Q

potential

A

stored energy

32
Q

when energy is produced

A

Heat results

33
Q

1st law of thermodynamics

A

Law of conservation of energy. Energy can not be created nor destroyed only changed from one form to the other

34
Q

2nd law of thermodynamics

A

Energy can not be changed from one form to the other without a loss of useable energy.

35
Q

Entropy

A

Amount of disorder; with every transformation the cells become less organized.

36
Q

Metabolism

A

sum of all chemical reactions that occur in a cell

37
Q

Example of metabolism

A

A+B (Reactant)—–D+C (Product)

38
Q

Metabolic pathways

A

series with linked reactions beginning with a particular reactant stopping with an end product.

39
Q

Products in one reaction will become what in the next?

40
Q

Enzymes are?

A

proteins that speed up chemical reactions; will combine with substrates.

41
Q

Substrate

A

is a reactant in a reaction for an enzyme

42
Q

Enzyme & substrate shape when they join together

A

Lock & Key model

43
Q

where does the reaction occur on a Enzyme and substrate?

A

the Active site

44
Q

What does warm temperature do to a reaction?

A

Speeds it up

45
Q

What does cold temperature do to a reaction?

A

Slows it down

46
Q

What does hot temperature do to a reaction?

A

Stops the rate

47
Q

What will denature protein and change its shape

A

Extreme heat

48
Q

Every reaction has a PH but a extreme PH will do what to the reaction?

A

Denature and stop the reaction

49
Q

What should you expect if you increase enzyme

A

more reaction

50
Q

list the 4 factors of reactions

A
  1. temperature 2. PH 3. Amount of Enzyme 4. Amount of correct substrate
51
Q

Enzyme suffix word

52
Q

what is enzyme inhibition?

A

when the enzyme is prevented from combining with its substrate

53
Q

examples of enzyme inhibitions

A

Poisons (cyanide) Antibiotics
