ATP is involved in both sliding filament mechanism and in the maintenance of calcium pump.

**Step-by-Step Solution:** 1. **Understanding Muscle Contraction**: Muscle contraction is primarily driven by the sliding filament mechanism, which involves the interaction between actin and myosin filaments. 2. **Role of Calcium Ions**: The process begins with calcium ions (Ca²+) being released from the sarcoplasmic reticulum. These calcium ions bind to troponin, a protein complex associated with actin filaments. 3. **Exposure of Binding Sites**: When calcium binds to troponin, it causes a conformational change that exposes the active binding sites on actin filaments. This allows myosin heads to attach to these sites. ...

The Hunsdiecker reaction is believed to proceed by a free radical mechanism and involves the formation of an acyl hypohalite. The major product is :

`Ph - CH = CH - undersetoverset(|)(CH_3) - Br`

`Ph - oversetunderset(|)(Br)(C ) H - CH = CH - CH_3`

`Ph - CH = oversetunderset(|)(Br)( C) - CH_2 -CH_3`

`P - CH = CH - undersetoverset(|)(CH_3)(C )H - CH_2 Br`
