PtichkaEL [24]

Answer:

1. Muscle Fibers

2. Bones

3. Joints

Explanation:

Muscle tissue is made of muscle fibers. The plasma membrane of a muscle fiber is called sarcolemma while its cytoplasm is known as sarcoplasm. Muscle cells are characterized by the presence of specialized endoplasmic reticulum which is called sarcoplasmic reticulum.

Muscle cells exhibit contractility and extensibility. The ability of muscle cells to shorten their length forcibly in response to a stimulus is their contractility. Muscle fibers have the ability to extend and shorten themselves.

Extension and contraction of muscle fibers are responsible for the movement of the human body and its parts.

Muscles are attached to bones via tendons which in turn are the fibrous connective tissues. Muscles are also part of our joints where they assist in the movement by pulling the bones as well as stabilize and strengthen the joints.

Why do organisms without oxygen need to convert pyruvate to lactate?
IrinaK [193]

The question is incomplete. The complete question is:

Question: Why do organisms without oxygen need to convert pyruvate to lactate?

A) because pyruvate is toxic to the cells

B) in order to regenerate NAD+

C) in order to use lactate in the citric acid cycle

D) because lactate is needed to produce ATP

Answer:

B) in order to regenerate NAD+

Explanation:

Kreb's cycle and electron transport chain (ETC) are the aerobic stages of cellular respiration. ETC regenerates NAD+ and FAD+ by oxidation of NADH and FADH2 produced during glycolysis and Kreb's cycle. Here, oxygen serves as the terminal electron acceptor.

Glycolytic reactions use NAD+ as an electron acceptor and produce NADH. Therefore, a constant supply of NAD+ is required to sustain glycolysis. In absence of oxygen, ETC cannot occur and organisms convert pyruvate into lactate. Pyruvate is reduced in lactate and NADH serves as the electron donor. Thereby, lactate fermentation regenerates NAD+ to continue the process of glycolysis.
