Question

1. produce protein antibodies that bind to foreign proteins to fight off infection. red blood cells white blood cells plasma hormones 9) resistance exercise (or weight training) enhances positive protein balance. true false 10) enzymes are proteins that prevent chemical reactions from occurring. true false

Explanation:

1. White blood cells, specifically B - lymphocytes, produce antibodies to fight infections. Red blood cells carry oxygen, plasma is the liquid part of blood, and hormones are chemical messengers not related to antibody - production for fighting infections.
2. Resistance exercise stimulates muscle protein synthesis, which enhances positive protein balance.
3. Enzymes are proteins that catalyze (speed up) chemical reactions, not prevent them.

Answer:

1. White Blood Cells
2. True
3. False
