In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
sugar |
|
mitochondria |
|
oxygen |
|
water |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
Which of the following does not represent the freezing point of water?
0°C |
|
32°F |
|
273K |
|
0°F |
The Fahrenheit scale fixes the freezing point of water at 32°F, the Celsuis scale at 0°C, and the Kelvin scale at 273K.
In cell biology, what part of the cell contains organelles?
cell membrane |
|
cytoplasm |
|
cell wall |
|
nucleus |
The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles.
In the pancreas, lipase converts fat to:
glycerol and fatty acids |
|
amino acids |
|
complex carbohydrates |
|
simple sugars |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
Neurons are part of the __________ nervous system.
peripheral |
|
central |
|
somatic |
|
autonomic |
The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.
