What is the primary function of anaerobic respiration?
To produce energy without oxygen
Anaerobic respiration occurs in environments where oxygen is not present.
What are the end products of anaerobic respiration?
NADH, 4 ATP
These products are crucial for energy transfer in cells.
Fill in the blank: The _______ membrane is rich in proteins compared to the external membrane.
internal
The internal membrane plays a significant role in cellular processes.
True or False: The internal membrane contains fewer proteins than the external membrane.
False
The internal membrane is actually richer in proteins.
What is the role of transport proteins in cellular membranes?
Facilitate the movement of substances across membranes
Transport proteins are essential for maintaining cellular homeostasis.
Define the term ‘permeable zone’ in cellular membranes.
Areas that allow certain substances to pass through
This is important for regulating the internal environment of the cell.
What are the characteristics of the internal membrane?
- Rich in proteins
- Has specific transport functions
These characteristics enable the membrane to perform critical cellular functions.
Fill in the blank: The _______ membrane separates the internal contents of the cell from the external environment.
external
The external membrane is the first line of defense for the cell.
What is the significance of NADH in cellular respiration?
It acts as an electron carrier
NADH is vital for the energy production processes in cells.
What does FADH represent in cellular respiration?
Another electron carrier similar to NADH
FADH plays a role in the electron transport chain.
What is the function of the ‘permeability zone’?
Allows selective passage of molecules
This zone is critical for the regulation of substances entering and exiting the cell.
List the components involved in the electron transport chain.
- NADH
- FADH
- Electron carriers
These components work together to produce ATP through oxidative phosphorylation.
True or False: The presence of transport proteins is unimportant in the function of cellular membranes.
False
Transport proteins are essential for the proper functioning of cell membranes.
What does ‘ATP’ stand for?
Adenosine triphosphate
ATP is the primary energy carrier in cells.
Fill in the blank: The _______ membrane contains enzymes that facilitate metabolic reactions.
internal
Enzymes in the internal membrane are crucial for various biochemical processes.
