Answer: Flow of electric charges- current
Opposition to the flow of electric current- resistance
Stored potential energy at the source of a circuit- Voltage
Explanation:
Answer:
Glycolysis and the TCA cycle are linked by the linking reaction catalysed by pyruvate dehydrogenase complex. Pyruvic acid produced at the end of glycolysis is transported to the matrix of mitochondria, where it undergoes oxidative decarboxylation to produce acetyl CoA. Acetyl CoA enters the TCA cycle.
Answer:
b) Channel pumps
Explanation:
The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.
For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.
Answer: D - Lipids
Lipids provide a long term energy storage because they contain longer C-H bonds compared to the other organic molecules, making it easier for them to store larger amount of energy. Moreover, upon burning they produce twice the amount of calories compared to that of the carbohydrates.
