Name two differences between prokaryotic and eukaryotic cells.
- Prokaryotic cells do not have a nucleus, whereas eukaryotic cells do.
- Prokaryotic cells are smaller and simpler in structure compared to eukaryotic cells.
What is the function of the mitochondria in a cell?
Mitochondria are responsible for aerobic respiration, producing energy in the form of ATP.
What is cell differentiation and why is it important?
Cell differentiation is the process by which cells become specialised to perform specific functions. It is important for the development and functioning of multicellular organisms.
How does a bacterial cell differ from an animal cell?
- Bacterial cells lack a nucleus and store their genetic material in a single circular DNA strand.
- Bacterial cells have a cell wall, while animal cells do not.
Describe the key difference between active transport and diffusion.
Active transport requires energy to move substances against a concentration gradient, while diffusion is a passive process where substances move from a high to a low concentration.
Why do muscle cells contain more mitochondria than skin cells?
Muscle cells require more energy for contraction and movement, so they have more mitochondria to generate ATP through respiration.
What is the difference between aerobic and anaerobic respiration?
- Aerobic respiration requires oxygen and produces more energy (ATP).
- Anaerobic respiration occurs without oxygen and produces less energy, with lactic acid as a by-product in animals.
What is the lock and key model in enzyme action?
The lock and key model suggests that an enzyme’s active site is specifically shaped to fit a particular substrate, ensuring only the correct substrate can bind and undergo a reaction.
What happens to an enzyme if it is exposed to very high temperatures?
The enzyme denatures, meaning its active site changes shape, preventing it from binding to its substrate and losing its function.
Name one type of specialised cell and explain how its structure is adapted to its function.
Root hair cell: Has a long, thin extension to increase the surface area for absorbing water and minerals from the soil.
Red blood cell: Has no nucleus to maximise space for haemoglobin and is biconcave to increase surface area for oxygen transport.
