The relation between gas and star formation at kiloparsec scales serves as a crucial link connecting our understanding of star formation at the molecular cloud level to the broader galaxy characteristics. This presentation highlights our research efforts focused on the resolved star-formation scaling relations in two distinct galaxy populations: the star-forming main sequence and green valley galaxies based on analyses of data obtained from the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey. Furthermore, I will also talk about our recent work studying the dense gas component at kiloparsec scales using ALMA HCN and HCO+ observations in five ALMaQUEST galaxies, shedding light on the quenching mechanisms within green valley galaxies.
