Text Solution

The correct Answer is:
To identify the wrong statement from the provided options, we need to analyze each statement carefully. 1. **Proton motive phase derives the universe movement of NO3 ions**: This statement suggests that the proton motive force (PMF) is responsible for the movement of nitrate ions (NO3-) across membranes. The PMF does indeed play a role in the transport of ions, including nitrate, by creating a gradient that can drive their movement. Thus, this statement is correct. 2. **Cotransport is against their own concentration gradient**: Cotransport, also known as secondary active transport, can involve the movement of one substance against its concentration gradient while another substance moves down its gradient. This statement is somewhat misleading because cotransport itself can be either symport (both substances move in the same direction) or antiport (substances move in opposite directions). However, it does not necessarily imply that all cotransport is against the concentration gradient. Therefore, this statement is potentially incorrect. 3. **Acids inhibit the process of respiration**: This statement is generally true. High concentrations of acids can disrupt cellular respiration by affecting enzyme activity and metabolic pathways. Thus, this statement is correct. 4. **ATPase serves as proton respiration carrier protein**: ATPases are enzymes that catalyze the hydrolysis of ATP, and some types of ATPases (like F-ATPases) do indeed function in proton transport across membranes. This statement is correct. Based on the analysis, the statement that is most likely to be incorrect is **"Cotransport is against their own concentration gradient."** ### Final Answer: The wrong statement is: **Cotransport is against their own concentration gradient.**
