Alexandra Palace will host the fencing events, while tennis will take place at Wimbledon with archery at Lord's cricket ground.
The Millennium Dome is set to host gymnastics, trampolining, basketball and handball, while triathlon and road cycling, baseball and softball, equestrian, modern pentathalon riding and running events will take place in key London parks.
Excel will stage the boxing, weightlifting, judo, tae-kwondo and wrestling in four auditoriums that will each seat 10,000 people.
Plans for new sporting facilities at an Olympic Park at Lower Lea Valley in east London comprise an 80,000-seat stadium, an aquatic centre and a velodrome.
London's bid is second favourite behind Paris. New York and Moscow are also in the running.
Excel chief executive and board member of Visit London Jamie Buchan said: "Visit London is working closely with the Olympic bid team to make sure we win. London is an attractive city that people want to come to and it has the edge over Paris in terms of tourism. The Government is behind the provision of infrastructure and transport development to make the games possible in this part of the city."
Outside the capital, the men's and women's football matches will take place at Hampden Park in Glasgow, Old Trafford in Manchester and Newcastle's Villa Park. The finals will take place at the new Wembley Stadium.
The winning city will be announced in July 2005.
