What kind of muscle tissue has the most mitochondria in it?
Type I muscle fibers
When viewed under a microscope a sample of tissue reveals striations and long thin fibers that contain many nuclei and mitochondria. What type of tissue is most likely being viewed?
The tissue most likely being viewed is skeletal muscle tissue. Skeletal muscle tissue is composed of long and thin fibers called muscle fibers that exhibit striations due to the arrangement of contractile proteins. These muscle fibers contain multiple nuclei and mitochondria to support their high energy demands.
How many mitochondria are there in skeletal muscle?
It depends on the type of skeletal muscle. Slow and fast oxidative fibers (type I and type IIa) may have many mitochondria. Fast glycolytic fibers (type IIx/IIb) have very few mitochondria. This is because in fast glycolytic fibers (type IIx/IIb) ATP can be produced outside of the mitochondrion in the cytosol of the cell due to high concentrations of glycolytic enzymes present in these fibers. In contrast, in oxidative fibers ATP is produced mostly within the mitochondrion, so more mitochondria are needed to to produce large amounts of ATP. Also, the number of mitochondria in these cells can increase with adaptations to exercise conditioning.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What type of muscle fibers used in strength training?
imcomplitory muscle fibers
Are Type II muscle fibers aerobic?
FALSE
Activities such as swimming and running are most likely to stimulate development of what type of muscle fibers?
Slow, fatigue-resistant fibers
What type of embryological cell gives rise to muscle fibers?
What type of embryological cell gives rise to muscle fibers
What muscle fiber type typically constitutes the largest percentage of the total muscle fibers in most human muscles?
Skeletal muscles are the largest percentage of total muscle fibers in the human body.
What type of muscle fibers you need to develop for weight lifting competition?
Mary needs to develop her fast muscle fibers. In order to do this, she will need to have frequent, brief and intensive workouts. She also needs to create muscle hypertrophy which will create an enlargement of the stimulated muscle. She can gain this by repeated and exhaustive stimulation which will create more mitochondria.
What type of muscle would have the most mitochondria?
Well this is a pretty simply question for a very complex topic. Mitochondria can vary within a cell type depending on environmental and life history variables. Some cell types have high mitochondria density, but are quite small (sperm) and some have lower mitochondrial density but are much larger (muscle cells). Other cells, like intestinal wall lining for example, also contain a lot of mitochondria.
What is a fast fiber?
A Fast Oxidative Fiber is a type of muscle fiber with many mitochondria and capillaries. This type has a high myoglobin content. This type of muscle tires more quickly than the slow oxidative fibers and is an intermediate sized muscle. This muscle is good for sprinting and other short, fast-paced activities.
