The phrase "amount and efficiency" is correct and usable in written English.
It can be used when discussing the quantity of something in relation to its effectiveness or productivity.
Example: "The project was evaluated based on the amount and efficiency of resources utilized."
Alternatives: "quantity and effectiveness" or "volume and productivity".
Stomatal conductance has proven to be important in determining the amount and efficiency with which water is used by cereal crops and the productivity of those crops.
One of the most important factors affecting the properties of resulting nanoparticles such as size, morphology, amount and efficiency of drug loading and also drug release profile is the amount of FA groups grafted on the chitosan chains.
Patient groups did not differ significantly in the total amount and efficiency of polysomnographically defined sleep.
Soil organisms act as the primary driving agents of nutrient cycling, regulating the dynamics of soil organic matter, soil carbon sequestration and greenhouse gas emission, modifying soil physical structure and water regimes, enhancing the amount and efficiency of nutrient acquisition by the vegetation and enhancing plant health.

However, not all type of proteins can be transferred at equal amounts and efficiency.
To compensate for variations in input RNA amounts and efficiency of reverse transcription, data for each target gene mRNA of each sample were normalized by reference to the data obtained for the house keeping HPRT (GenBank accession no. X62085) determined from the same sample.
To compensate for variations in input RNA amounts and efficiency of reverse transcription, 18 s ribosomal mRNA was quantified and all results were normalised to these values.
However we note that this method has limitations due to loading of consistent spike-in amounts and efficiency of amplification of individual genes.
To compensate for variations in input RNA amounts and efficiency of reverse transcription, data for each target gene mRNA of each sample were normalized by reference to the data obtained for the house keeping HPRT (GenBank accession number X62085) determined from the same sample.
These standard, well-characterized iron oxide nanoparticles have been used widely, but low labeling amounts and efficiencies were shortcomings [ 35].
