How are chloroplast and mitochondria similar?
How are chloroplast and mitochondria similar?
Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis.
How are mitochondria similar to chloroplasts quizlet?
In mitochondria, ATP is produced as a result of oxidation and foodstuffs, and is used as an energy source for metabolic processes. In chloroplasts, ATP is produced as a result of harvesting energy from light. In chloroplasts, the ATP is used in the fixation of CO2 into sugars.
How are mitochondria similar to chloroplasts both have many layers?
Both mitochondria and chloroplasts are double membrane layered structure. They both have an outer membrane, inner membrane, and inter-membrane space. Mitochondria are present in cells of all eukaryotic organisms including plants. Thus, we can say that both are similar in having two layers of membranes.
What internal structure does a chloroplast have that isn’t found in a mitochondria?
Like mitochondria, chloroplasts have outer and inner membranes, but within the space enclosed by a chloroplast’s inner membrane is a set of interconnected and stacked fluid-filled membrane sacs called thylakoids (Figure 3). Each stack of thylakoids is called a granum (plural = grana).
What do Cristae do in mitochondria?
Function. The cristae greatly increase the surface area of the inner membrane on which the above-mentioned reactions may take place. A widely accepted hypothesis for the function of the cristae is that the high surface area allows an increased capacity for ATP generation.
Where is the Cristae located in mitochondria?
Cristae are located on the inner membrane of mitochondria and mitochondria are located in the cell cytoplasm, not the nucleus.
What are the two membranes of mitochondria?
As previously mentioned, mitochondria contain two major membranes. The outer mitochondrial membrane fully surrounds the inner membrane, with a small intermembrane space in between. The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein.
Why do mitochondria have double membranes?
The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane, which now contains numerous folds, apparently came from the bacterial membrane, while the outer membrane came from the host cell itself.
What is the function of the two membranes of mitochondria?
The membranes create two compartments. The intermembrane space, as implied, is the region between the inner and outer membranes. It has an important role in the primary function of mitochondria, which is oxidative phosphorylation. The matrix contains the enzymes that are responsible for the citric acid cycle reactions.
What is the other name of mitochondria?
chondrosome
What are ribosomes called?
Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus.
What’s inside a chloroplast?
The chloroplast has an outer membrane, an inner membrane, and membrane structures called thylakoids that are stacked into grana. The space inside the thylakoid membranes is called the thylakoid space. The fluid enclosed by the inner membrane that surrounds the grana is called the stroma.
