The SCL and SDA signals are driven by open-drain buffers and a pullup resistor is required to make the signals rise to the high

Higher resistance value pullup resistors consume less power, but have a slower the rise time (due to the RC time constant

pullup resistor is required in higher bus capacitance systems.
