True or False:When ATPase is run 'backwards' its purpose is to convert ATP to ADP to create a H+ gradient.
A
True
B
False
Verified step by step guidance1
Understand the function of ATPase: ATPase is an enzyme that typically uses the energy from ATP hydrolysis to transport ions across a membrane, often creating a gradient.
Recognize the concept of 'running backwards': When ATPase runs in reverse, it uses the energy from an existing ion gradient to synthesize ATP from ADP and inorganic phosphate.
Identify the role of ATP synthase: In cellular respiration, ATP synthase is a type of ATPase that works in reverse to produce ATP using the proton (H+) gradient across the mitochondrial membrane.
Clarify the direction of the process: If ATPase is running 'backwards', it is not converting ATP to ADP to create a gradient, but rather using a gradient to produce ATP.
Conclude the statement: Based on the understanding of ATPase function and directionality, determine whether the statement about converting ATP to ADP to create a H+ gradient is true or false.
