_________ threshold is also called the ________ threshold, the point at which lactic acid produced in muscles begins to accumula
Ne4ueva [31]

Answer:

1. Anaerobic

2. lactate

3. Aerobically

Explanation:

During excessive muscular activities such as a marathon, lactate fermentation occurs in muscles to serve as a source of ATP to sustain muscle contraction. The lactate produced during lactate fermentation is removed aerobically from muscles. Lactate threshold or anaerobic threshold refers to the intensity of physical activity that produces the blood lactate at a fast rate than its removal.

Increased intensity of exercise or physical activity increases lactate production. As the intensity reaches the point at which lactate cannot be removed from the body fast enough, it is accumulated and causes fatigue in muscles. Therefore, the lactate threshold is the upper limit that can be sustained aerobically by the body without any accumulation of lactate.

Genome

Explanation:

The genome of an organism is the summation of all the genes in the cells that hold information on how the organism is built and maintained. In higher organisms, the genome also contains non-coding regions that also play a significant role in the cells such as ensuring the integrity of chromosome ends. The genome of a human being is composed of approximately 3 billion base pairs.

The genome of organisms may not necessarily be found in the nucleus of cells, especially in eukaryotes,  but in addition can be found even in membrane-bound organelles like the mitochondria and chloroplast.
