1.核糖是ATP的组成部分，补充核糖有助于合成ATP。（√）
ATP由腺苷（腺嘌呤和核糖）和三个磷酸基团组成，核糖是ATP的组成成分，补充核糖可以为腺苷合成提供原料，间接支持ATP生成。
Ribose is a component of ATP, and supplementing ribose helps ATP synthesis. (√)
展开剩余83%ATP consists of adenosine (adenine + ribose) and three phosphate groups. Ribose, as a structural component of ATP, provides raw materials for adenosine synthesis and indirectly supports ATP production.
2.土豆中的过氧化氢酶可用于探究pH对酶活性的影响。（√）
过氧化氢酶的活性受到pH的影响，所以土豆中的过氧化氢酶可用于探究pH对酶活性的影响。
Catalase in potatoes can be used to investigate the effect of pH on enzyme activity. (√)
Since catalase activity is pH-dependent, potato-derived catalase can be used to study how pH affects enzyme activity.
3.糯米、大米蒸煮后立即与酒曲混合会导致酶空间结构改变而降低其催化效率。（√）
糯米、大米蒸煮后温度较高，立即与酒曲混合，高温会使酶的空间结构改变，导致酶活性降低，从而降低其催化效率。
Mixing steamed glutinous rice/rice with fermentation starter immediately after cooking causes enzyme denaturation and reduces catalytic efficiency. (√)
Steamed rice has a high temperature. Immediate mixing with fermentation starter (containing enzymes) denatures enzymes due to heat, damaging their spatial structure and reducing catalytic efficiency.
4.比较过氧化氢在不同条件下的分解，用“过氧化氢酶溶液”替代“肝脏研磨液”。（√）
肝脏研磨液中含有过氧化氢酶，所以在比较过氧化氢在不同条件下的分解实验中，能用“过氧化氢酶溶液”替代“肝脏研磨液”。
Comparing hydrogen peroxide decomposition under different conditions can use "catalase solution" instead of "liver homogenate". (√)
Liver homogenate contains catalase, so "catalase solution" can replace "liver homogenate" in experiments studying hydrogen peroxide decomposition.
5.酶作为生物催化剂，酶作用的反应物都是有机物。（×）
过氧化氢酶作用的反应物过氧化氢就是无机物
Enzymes, as biological catalysts, only act on organic substrates. (×)
The substrate of catalase (hydrogen peroxide) is an inorganic molecule.
6.淀粉酶在0℃时空间结构会被破坏。（×）
低温不会使蛋白质空间结构改变，淀粉酶本质为蛋白质，在0℃时空间结构不会被破坏。
Amylase spatial structure is destroyed at 0°C. (×)
Low temperatures do not alter protein spatial structures. Amylase, being a protein, retains its structural integrity at 0°C.
