the atp is generated by two methods in our body, one is oxidative phosphorylation which uses energy from reduction of NADH and FADH2, this is the major supply n for every NADH we make 3ATPS n FADH2 makes 2ATPS in ETC.NADH n FADH2 are produced in cytoplasm n to get into mitochondria under aerobic conditions need shuttle service.malate shuttle relys on NADH n G3P on FADH2 the no. of ATPs produced with both is different, malate n G3p shuttles are not electron transport chain but merily shuttles used to transport NADH n FADH2 energy across mitochondrial membrane. which then are used in the ETC. second method of ATP production is susbstrate-level phosphorylation which produces ATP directly from ADP but is low yeild as only 2 ATPS/glucose.this happens in glycolysis.in aerobic condition, glycolysis will proceed to TCA n Oxidative phosphorylation which will produce the major bulk of ATPs. glycolysis=2ATP/glucose+(1NADH)x2 for every glucose now if NADH uses malate shuttle it will produce 3ATPs n with G3P only 2.so total glycolysis ATPs under aerobic conditions ATP can be either 8 with malate or 6 with G3P.obviously these shuttles are needed
