Answer:
The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.
The gramicidn protein is an ionophoric antibiotic that can affect the electron transport system. The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell. But the ATP synthesis rate might decrease and completely stop by using gramicidin.
The enzyme pepsin functions with a very low pH of around 2. It is found in the stomach, with the acidity coming from the hydrochloric acid present there. it breaks proteins into amino acids.
Answer:
the answer is B
Explanation:
because pangaea was a super continent
D)independent
Explanation:
An independent variable is a variable that is changed to test the prediction in an experiment. Independent variables are the cause in an experiment. They are the ones that produces the effect.
- Changing independent variables produces different effects in an experiment.
- These effects are the dependent variables
- Independent variables do not depend on the outcome of the experiment.
- They are the ones that determines how a reaction proceed and what might likely happen.
