Anaerobic respiration in muscles produces Lactic acid and energy.

Here's the step by step process:

1. Glycolysis: This is the first step of anaerobic respiration, and it occurs in the cytoplasm. One glucose molecule (6 carbons) is broken down into two molecules of pyruvate (3 carbons each). This process produces a net gain of 2 ATP molecules and also generates 2 NADH molecules.

2. Lactic Acid Fermentation: If oxygen is not present, the pyruvate molecules produced in glycolysis will undergo lactic acid fermentation. In this process, the 2 NADH molecules are used to convert the 2 pyruvate molecules into 2 lactic acid molecules. This process regenerates NAD+ so it can be used again in glycolysis. No additional ATP is produced in this step.

So, the end products of anaerobic respiration in muscles are lactic acid and energy (in the form of ATP).
