Q

What does Light-dependent reactions need?

A
  • needs light
17
Q

What does Light-independent reactions need?

A
  • does not need water
18
Q
  • Where do Light-dependent reactions take place?
  • What goes in?
  • What comes out?
  • Where does the ATP and NADPH gp?
A
  • In the thylakoids of the chloroplast
    -sunlight and water
  • Oxygen, ATP, and NADPH
  • To the light- independent reactions
19
Q

What happens overall in the light-dependent reactions?

A
  • Chlorophyll absorbs energy from sunlight and is transferred to ATP and NADPH
  • The water is split and oxygen is released
20
Q
  • Where do light-independent reactions come from?
  • What goes in?
  • What comes out?
A
  • The stroma of the chloroplast
  • Carbon dioxide, (ATP and NADPH from light-dependent reactions)
  • Glucose (ATP and NADPH goes back to thylakoid to be recycled in the light-dependent reactions)
21
Q

What overall happens in light-independent reactions?

A
  • Carbon dioxide and energy from light-dependent reactions (ATP and NADPH) are used to make sugar glucose
22
Q

What is ATP and what is it used for?

A
  • Adenosine triphosphate is the energy carrying molecule of cells
  • used to power all types of cell processes
23
Q

How does ATP work?

A
  • Energy that is stored in the chemical bonds of this molecule and to release the energy, you have to break the bonds
24
Q

How to make ATP?

A
  • Aerobic - with oxygen
  • Anaerobic - without oxygen
25
Q
  • The definition of Cellular Respiration?
  • who does Cellular respiration?
  • Where does it take place?
A
  • The main process that converts glucose into ATP
  • Plants, animals, and other eukaryotes
  • Mitochondria
26
Q

What is the formula for Cellular Respiration?

A
  • C6H12O6 + 6O2 (Reactants) - ATP + 6CO2 + 6H2O (Products)
27
Q
  • Where does glycolysis take place?
  • What goes in?
  • What comes out?
  • Is glycolysis aerobic or anaerobic?
A
  • Cytoplasm
  • glucose
  • ATP, electrons, broken down glucose
  • anaerobic
28
Q

What happens overall in glycolysis?

A
  • Glucose is broken down into 2 pieces (pyruvate) that either the krebs cycle or and a little ATP is made. Electrons go to ETC.
29
Q

What happens in the krebs cycle overall?

A
  • The rest of the glucose is broken down and electrons that are extracted go to the ECT. A little ATP is made.
29
Q
  • Where does the krebs cycle take place?
  • What goes in?
  • What comes out?
  • Is the krebs cycle aerobic or anaerobic?
A
  • Mitocondria
  • broken down glucose
  • ATP, electrons
  • aerobic
30
Q

Where does the Electron Transport chain take place?
- What goes in?
- What comes out?
Is it aerobic or anaerobic?

A
  • Mitocondria
  • Electrons from glucose and oxygen
  • 32-34 ATP and water
  • aerobic
31
Q

What happens in the Electronic Transport Chain overall

A
  • Energy is transferred to a chain of proteins in the inner membrane of the mitochondria. The proteins use the energy to pump (Active transport) hydrogen ions against the membrane. ATP is created and water is formed.
